So, the first Friday football night of the Premier League season ends with Manchester United beating Southampton to take the three points - you can read the BBC match report here. Don't forget there are still nine more top-flight games to come this weekend, so more thrills and spills to follow.
- Ibrahimovic heads opener; then scores penalty
- Pogba plays first 90 minutes for Man Utd
- First of this season's Friday night PL games
Manchester United midfielder Paul Pogba to BBC Sport: "It's a great feeling, I'm very happy, it's my brother's birthday so I am happier,
"I was relaxed, no nerves, I played my game. I came here to win, that is what I always wanted. It's a top club, we need to get used to winning and carry on like this.
"First ball, I lost it, but got used to it. After that I felt better. We dream big. United are a big club, I know we will do big things this season."
Manchester United boss Jose Mourinho told Sky Sports: "We were good enough to deserve the victory and be in control. We won comfortably and the result could have been bigger.
"It's a natural evolution, step by step. It's impossible to demand more from the boys. It's a great spirit with everyone working really hard.
"Zlatan Ibrahimovic is very good in the air. But he's great with his feet. I'm really happy with his performance.
"Paul Pogba was so good. He's learning how to play with us. I'm very happy. [In some games] he can play even more offensively than he did today. He needs the freedom he had. I couldn't be happier with him. In my opinion Marouane Fellaini was superb."
Southampton had 10 shots at United's goal (not counting two others that were blocked) but David de Gea had only one save to make... from Shane Long's first-half daisy cutter that is shown by the green circle below.
Manchester United midfielder Paul Pogba completed the 90 minutes and told Sky Sports: "It's great. I'm very happy for the team. I hope to carry on like this, getting better and keep on winning. I feel very good."
Manchester United striker Zlatan Ibrahimovic's post-match interviews so far have been very notable for the lack of ego.
He told Sky Sports: "If the team does good, the individuals do good. I try to do what I'm best at, helping my team-mates, creating chances and scoring goals.
"I'm happy for the team. We are becoming better and better. It's a good start. We need to get used to winning, the mental part is important. I need to get to know everybody and the way we play. Everything is new. It's like a big parcel. We need to put the parcel together.
"Here the game is tougher [than France] and you need to work through the game. When the possibility comes you need to be focused. It doesn't matter who scored."
Paul Pogba's first game for United since his return for an £89m world-record fee sees him make more touches (103) and win more duels (20) than any player on the pitch.. Only Southampton's Pierre Hojbjerg (85) played more passes than his 71 while Pogba covered 11.2km, the third highest distance.
The stats show Southampton had more possession, but United controlled the game.
Dundee moved joint top of the Scottish Premiership table but missed a chance to go two points clear as they were held at home by Hamilton.
Darren Lyon fired a surprise opener for Accies with a superb 25-yard effort.
But the visitors left the impressive Mark O'Hara unmarked to side-foot home Danny Williams' corner minutes later.
United were top of the table on goal difference after the first round of games last weekend. Seeing as no-one else has played again since, and they have just won, do I need to tell you they are still top?
What I will tell you is that it is ridiculously early to be looking at the table and getting excited. So stop it.
Two Premier League wins from two games for Manchester United. Southampton cannot make it three wins from three visits to Old Trafford.
Credit to Southampton they are still chasing every ball and almost capitalize on an Eric Bailly error after he tries to run the ball out of play.
United still look dangerous, though, and Paul Pogba clearly wants a debut goal. He gets plenty of power behind his strike from a Henrikh Mkhitaryan's pass, but he is a long way out and a fair way off target.
The 90 minutes are up - there will be three minutes of stoppage time at Old Trafford.
Ray O'Brien: Can I be the first to tell you lot to calm down? Utd won their first two games last season, let's not forget
Jeff Kraus: Don't worry Man U fans... you will soon grow tired of Mourinho antics and so will your players
Taylor: Sure JM was expecting a better atmosphere than this after his midweek rallying cry So quiet in Old Trafford
Paul Pogba is going to last 90 minutes on his full debut because United have made their third and final change.
Wayne Rooney's 600th club appearance is over, and Chris Smalling is on instead for the final few minutes.
Southampton have had nine shots tonight, but only one on target. Their latest effort to fly wide came from Dusan Tadic, who met a fizzed Matt Targett cross on the edge of the area but did not trouble David de Gea.
Five minutes to go, and United are in control. Paul Pogba included, they have been solid, rather than spectacular tonight... but a third Zlatan Ibrahimovic goal would change all that.
Saints' turn to make a change. Shane Long does not exactly look delighted as he walks off, with Jay Rodriguez looking a lot happier as he sprints on.
Another United change and it appears Paul Pogba is going to last 90 minutes on his first ever start for the club.
Ander Herrera is on, Anthony Martial is off. Jose Mourinho has got one more substitution to make.
United are sitting back and looking to spring at Saints on the break. They are not having much joy when they do look to counter but their defence looks solid and they have got about nine minutes of the 90 to hold out before they can say job done.
Saints played their last free-kick short when they had a chance to put it in the United area, this time they do hoist it in. Pierre Hojbjerg's delivery finds Virgil van Dijk, too, but he is under pressure and his header loops over the bar.
Ash Jung: I'm actually concerned that every Man Utd Premier League game this season will be an exhibition match. Terrifying firepower.
Sir_Loin: I have to say, some of the football Man Utd have played tonight has been sublime. What a refreshing change!
Andy Crossman: Man Utd spend £89m on one player and the prawn sandwich brigade think they are great again!!!
Better from Southampton, with Shane Long spinning at the near post to find some space but his flicked header still drifts wide and David de Gea has not had very much to do... just one shot on target by the visitors so far.
Time for a United change... Paul Pogba? No... it is Juan Mata who goes off, replaced by Henrikh Mkhitaryan.
Same old story for Saints. They are playing some neat passes but cannot find a way through.
Anthony Martial is coming into this game more and more as things open up, covering a lot of ground as he flies forward from the left almost to the opposite flank. He is eventually held up but United still put in a cross, via Antonio Valencia, that finds Zlatan Ibrahimovic at the far post. His header loops up rather that at goal, however, and he is offside in any case.
Saints are going for it here... they have to really. Charlie Austin, a striker, is on for midfielder Steven Davis.
Bekers1995: Who cares about the Olympics?! This season's Premier League is going too be a bomb!
Conwa: Is this the largest collective of ego maniacs to ever be associated with a single team? #ManchesterUnited
Varun Sharma: When I see our United squad and think what Louis van Gaal used to do -Young as CF really?? He was clueless. Zlatan is the real deal.
United come forward again as Anthony Martial gallops goalwards from the left. This looks dangerous, but his shot is blocked. The game is getting stretched, though, and Saints are leaving bigger gaps at the back as they send more men further forward.
Another United goal would finish this game off though... and one for Paul Pogba would possibly take Zlatan Ibrahimovic off some of tomorrow's back pages. He rises well to meet Juan Mata's corner but cannot keep his header down.
Less than half an hour to go. Southampton have not given up yet and have a sniff when Zlatan Ibrahimovic loses the ball in his own half.
The visitors have plenty of men forward but again United keep them at bay and Saints end up playing it back to Jordy Clasie, who is arriving at speed near the edge of the box but sees his first-time shot fly wide of goal at an even greater velocity.

It may be the curse of the commentator, but I think this game is dead and buried. I can't see Southampton getting back into this one. They had a good two or three-minute spell at the start of the second half, but their hopes of mounting a recovery have been undone by the second Manchester United goal.
Ah, no - rather than put it into the mixer, Saints choose to try to play it in. Initially they are forced back but then work it wide and this time find a dangerous cross from the right. It comes to Nathan Redmond at the far post, who has time to bring it down, but then over-elaborates and mis-cues in quick succession. Chance gone.
Saints look dangerous when they come into the United half but apart from that disallowed goal they still seem to get snuffed out when they get near the home area. Still, they have a chance to put the ball into the danger zone now because they have a free-kick about 40 yards out.
Obajiotareh: Zlatan was already celebrating before the ball hit the back of the net
Peter Collins: The more I watch Luke Shaw, the more I think that at £30m, Man Utd have a top full-back for the next decade. Very good player.
Craig Andrew Smith: Can teams please start gifting Sunderland goals like they are doing for Man Utd? Seriously what was Clasie thinking?
It looks a long way back from here for Southampton. I don't know how many times a Jose Mourinho team has surrendered a 2-0 lead at home but my guess is not very often. Not much of a stat, granted, but if anyone wants to work it out please let me know!

Blatant penalty. Why is Jordy Clasie making the challenge? It was such a silly thing to do.
I think with the spot-kick, it may have been a case of: "I am Zlatan, I take the penalties." Wayne Rooney didn't argue.
Zlatan Ibrahimovic steps up to take the spot-kick and sends Fraser Forster the wrong way to double his tally tonight and extend United's lead. He seems to like English football, doesn't he?
Luke Shaw goes down in the box under a challenge from Jordy Clasie.
