- Celtic move 11 points ahead of Aberdeen
- Aberdeen must win on Saturday or Celtic are champions
Dundee manager Paul Hartley
"When you come to Celtic you try to stay in the game as long as you can but tonight we faced a very good Celtic team. The first goal is always vital. We felt we could have avoided it, allowing the cross to come in. Two of our key players were missing tonight (Stewart and McGowan). We have tried to give the players a strong mentality. We want to get as many points as we can. We are on a run of four defeats but we have played good teams. Players are always playing for their future; that's those in contract and out of contract."
Celtic manager Ronny Deila
"We like those goals (Celtic's second involved every single member of the team without a Dundee player touching the ball) but also the quick ones. We will follow the Aberdeen game, of course. It is hard to play at Dundee United. We have put ourselves in a good position. We had full control all the time. We had another clean sheet."
Leigh Griffiths tells BBC Radio Scotland that he will continue to work hard at Celtic and hopes to catch the eye of Scotland manager Gordon Strachan.
Winger James Forrest cracks in Celtic's fourth goal of the evening.
Rugby final score: Edinburgh 13-19 Gloucester.
That is the first time this season that the Dees have lost by five goals. It's a painful evening for them as they were outclassed by the champions elect. Nir Bitton's goal, Celtic's fifth, was a peach.
What a screamer of a goal by Nir Bitton. The Israeli midfielder picks up the ball 25 yards from goal and nonchalantly strikes it into the top corner of the Dundee net. That lad Ronaldo would have been proud of that - he couldn't have hit it more sweetly.
Luka Tankulic tries to do to Celtic what James Forrest did to Dundee, with a pacy run into his opponents' half. However, his shot sweeps across the face of goal and goes wide.
In Glasgow, there are five minutes to go. Celtic will be 11 points clear of second-place Aberdeen, and the Dons, with four games left, know they must beat Dundee United tomorrow or Celtic are champions.
Rugby update: Gloucester are down to 14 men in Edinburgh's European rugby final. The Scots have about six minutes to pin Gloucester back. They trail 19-13.
Mikeybhoy77: "Fisher's contribution in 5 minutes more than that of Ambrose in over an hour #bbcscotfootball"
Kris Commons scores from the penalty spot to make it 3-0 for Celtic.
BBC Scotland football pundit Murdo MacLeod
"You have to give the credit to Celtic tonight - their attitude has been top class."
No Dundee player can catch James Forrest as he sprints clear and bears down on the visitors' goal before drilling a low shot past Scott Bain.
Rugby update: With under 15 minutes to go in their European Challenge Cup final, Edinburgh trail Gloucester 19-13.
Stefan Scepovic is next to get a run-out, with Leigh Griffiths heading off to applause from the Celtic fans.
Kris Commons makes no mistake from the spot and Celtic are one slip-up by Aberdeen away from winning the Scottish Premiership...surely.
A foul by Stephen McGinn on Darnell Fisher results in a penalty for Celtic.
Leigh Griffiths's free-kick from out on the right is attacked by Virgil van Dijk but it comes to nothing. Dundee still don't look like threatening the Celtic net but they have at least stemmed the loss of goals.
A moment ago, Calvin Colquhoun replaced Alex Harris for Dundee.
Celtic manager Ronny Deila makes two changes - James Forrest and Darnell Fisher come on for Stefan Johansen and Efe Ambrose.
Rab McCutcheon in Benalmadena Costa del Sol, Rangers fan: "Congratulations to Celtic for winning the league. Just don't get too used to it."
Laura Shanahan, Glasgow: "It's ridiculous to think there's anything other than poor decisions that happen to every club. You can't be bitter about it and I'm a Celtic fan, video replays?"
Ozzy, West Bromwich: "Re Jim 20:51. Yes, like the Hamilton game this season. Clear goal not given and blatant penalty not awarded. Would never happen to anyone other than Celtic."
And Dundee goalie Scott Bain has to be lively to deny Gary Mackay-Steven, racing from his line to smother a toe poke from the twinkle-toed winger.
Thomas Konrad's clearance from the penalty spot lands straight at the feet of Stefan Johansen but his swipe at goal from 18 yards is panicky and whizzes high and wide of Scott Bain's goal.
Virgil van Dijk, with confidence oozing, swaggers forward down the left and cuts inside before making a hash of a curling effort. Perhaps he is bored at the back for Celtic this evening.
BBC Scotland football pundit Murdo Macleod
"He's been a wee bit quiet tonight, Gary Mackay-Steven. He could be first for the hook if Ronny Deila wants to make changes."
Kris Commons drives a corner kick firmly to the near post area where Celtic centre-half Virgil van Dijk heads for goal but misses the target.
We'll have highlights of the match on the BBC Sport website at midnight. It's been a quiet start to the second half, mind you.
Scott Bain, resembling the Pink Panther in the Dundee goal, appeals to his team-mates to show for the ball. No-one does so to Bain's satisfaction and instead he thunders a kick-out up the pitch.
Jim in Glasgow hits back: "What I'm saying is Celtic get the least amount of correct decisions than any other club in Britain!. Lots of the decisions by the officials are just blatantly atrocious not ' poor refereeing'!. These shocking decisions change games! The SFA is rotten to the core!!!"
Former Celtic assistant manager Murdo MacLeod
"Dundee have got to get support to the striker but you get the feeling they are really just wanting to stop Celtic scoring more goals."
Scott Brown issues a motivational speech to his team-mates in the Celtic huddle and it is those players who kick off the second half.
Anonymous Aberdeen fan: "Well done Aberdeen, magnificent effort to stay close to Celtic for so long, a very happy city just now. A new goalie a must next season though."
Scott Brown scores Celtic's second to put the home team firmly in charge.
Leigh Griffiths celebrates leaping to nod Celtic in front in a largely one-sided first 45 minutes.
This near enough burst my head this afternoon - a guide towhat can be decided and who needs what in each division tonight and tomorrow across the four SPFL leagues. Thanks to David Currie for sharing the burden.
Mac from Alva: "Well Jim from Glasgow you got a penalty that never was at Tannadice last week so cheer up."
Mal North Antrim: "Re Jim from Glasgow - sure they are employed by the SFA and are tasked to give us SFA. An honest mistake requires honesty."
David de la Fawkes: "#bbcscotfootball exactly. Celtic NEVER get any decisions. Ever. Every other fan of every other team agrees. Completely." Hmm.
