The Kop confetti had barely been swept away and the champagne hangovers had just worn off when Ole Gunnar Solskjaer vowed to knock Liverpool off their Premier League perch again.
The league title going to Anfield for the first time in three decades stung Manchester United, the 33-point chasm between these bitter rivals in the final table symbolic of a power shift.
Jurgen Klopp's Liverpool winning the Champions League and then the Premier League in consecutive seasons only hammered home how far United had declined from the time when Sir Alex Ferguson made winning look as easy as breathing.

'Every time you see anyone else lift a trophy, it hurts. That's the feeling everyone associated with Manchester United,' Solskjaer said a few days after Liverpool's title coronation.
'We want to get back to winning ways. That is our challenge.'
While United's third-placed finish in 2019-20 hinted strongly at progress, nothing suggested they would enter this Sunday's clash with Liverpool at Old Trafford four places and 13 points above them.
It isn't a full reversal of last season's colossal gap but an impressive swing nonetheless and United need just a point from the game this weekend to guarantee they will finish above Liverpool.
What's more, Solskjaer's team find themselves in the nice position of knowing any points taken on Sunday will deal a blow to Liverpool's chances of qualifying for next season's Champions League.

But Liverpool's title defence has been risible amid a season of injury frustrations

While United look set for a second-place finish, albeit a distant one to champions-elect Manchester City after their title challenge spluttered, Liverpool are caught in a top-four bottleneck.
They're duking it out with Chelsea, West Ham, Tottenham and Everton for what is essentially one remaining Champions League place.
Liverpool's nine league defeats this season is as many as in their three previous seasons combined and far from where they expected their title defence to be with five rounds of games to play.
But are we witnessing a long-term pendulum swing back from Merseyside to Manchester? In truth, it's too early to say.
The 1970s and 1980s belonged to Liverpool before Ferguson's United dominated the two decades that followed. The seven seasons since Fergie's retirement have seen greater unpredictability.
