Scottish football: Rob Maclean on Celtic, Aberdeen, Bjorn Johnsen, Joe Garner
BBC Scotland football commentator Rob Maclean looks at the key themes to emerge from the weekend's football.
Celtic look unstoppable
All you'll get from the bookies now is skinny odds if you want to back a Celtic treble this season and, for me, they have the look of an unstoppable force in pursuit of the clean sweep.
Of course, the Scottish Cup, the only trophy they haven't either won or are a racing certainty to win, has been known to throw up a shock or two.
- Rodgers the 'messiah' as Aberdeen flop
- Rodgers wants another century of trophies
- Pat Bonner and Willie Miller's cup final player ratings
Celtic could have a bad day, their opponents might be firing on all cylinders, it's 11 against 11, as the book of cliches tells us. Yes, a cup shock is possible after the turn of the year but you wouldn't bet on it.
Not against a Celtic squad which has lost the vulnerability it frequently showed over the last couple of years. The Brendan Rodgers revolution has kicked in to considerable effect and his team's unbeaten domestic record this season will take some stopping.
You did get the feeling, as Celtic won emphatically against Aberdeen on Sunday to take delivery of the League Cup and tick the first box of three, that the winning is only just beginning.
Aberdeen were swatted aside by treble-chasing Celtic at Hampden more like a minor irritant than a major rival.
It was a bitterly disappointing day for the Dons who know Scotland's top team won't be caught in their latest title defence but saw the League Cup final as a big one-off opportunity to upset the odds.
Aberdeen appeared to play without any real belief that they could beat Celtic. They failed to assert themselves in the early exchanges, handing the initiative to the opposition and the tone was set for most of the match.
When they did impose themselves in the game for a spell in the second half, they were already two goals down and a comeback was somewhere between highly unlikely and completely impossible.
To lose to slick Celtic is clearly no disgrace. It's the manner of the defeat which will rankle with Aberdeen. Too many of their top players failed to perform anywhere near their best.
Can Johnsen regularly hit the heights?
There's one very big reason for Hearts fans to think they've found a striking solution to the goal drought suffered by their main attackers so far this season.
Beanpole Bjorn Johnsen scored twice in the 3-0 home win against Motherwell on Saturday and looked unlucky when an offside flag denied him another goal with a cleverly-placed header.
Coach Robbie Neilson and director of football Craig Levein have always been confident that the 6ft 5in New York-born front man would eventually deliver the goods.
And the quality and composure Johnsen showed in slotting home his first goal at the weekend promised much for the coming weeks and months.
Generally speaking, goals haven't been a problem for Hearts. Only Celtic have scored more in the Premiership. But a prolific striker wouldn't do any harm.
Dodoo looks better than the average Joe
Rangers could do with a regular goalscorer as well and it looks like it's time for Big Joe to take over from Wee Joe.
Former Leicester youngster Joe Dodoo's half-hour cameo appearance off the bench at Firhill produced two goals and turned a possible defeat at the hands of Partick Thistle into a 2-1 win.
His first goal was particularly impressive, a rasping right-foot volley to level things up in the 81st minute and pave the way for Dodoo's winner with the last kick of the game.
He'd replaced the pretty ineffective Joe Garner who doesn't, so far, look anything like the £1.8m Rangers spent on him.
The Rangers fans don't want an average Joe up front and the lanky Dodoo looks the better option at the moment to be the focal point of the attack.
Where every point's a prisoner
You could throw a blanket, if you were so inclined, over the Premiership's not-so-magnificent seven who could finish the season with anything from relegation to a top-six place.
So it's certainly not a comfort blanket for those teams currently filling positions six to 12 in the league table who are separated by only two points.
The only winner among them at the weekend was Dundee. It's so tight in the lower reaches that a home win against Inverness Caley Thistle took Paul Hartley's team from bottom of the Premiership to the brink of the top half.
Partick Thistle, with 10 minutes to go at Firhill, were poised to leap six places. Losing two late goals sent them back to the bottom.
If that concertina effect for those seven teams continues for the rest of the season we could be in for an exciting, if nail-biting, conclusion. At least it's competitive at that end of the league.
