Manchester United fans hope that Man City's historic treble win will be a wake up call to the club and make them realise what will be required to reach the top again.
City became the first team in England to ever claim all three domestic trophies available to them in a single season and they did so in devastating fashion.
The Blues trounced Watford 6-0 - equaling Bury's record from 1903 for biggest FA Cup final victory - through goals from David Silva, Kevin De Bruyne and two each for Gabriel Jesus and Raheem Sterling.
It brings an incredible season, in which City have also lifted the Carabao Cup and the Premier League, to and end in the perfect way.
It's in stark contrast to how United ended their season, as they only managed to pick up two victories in their final 12 games in all competitions.

Optimism was initially high following the brilliant start of Ole Gunnar Solskjaer's reign at the club but that quickly dwindled along with the results, with the job ahead of the United boss this summer laid bare.
The two clubs couldn't be further apart at the moment, and United fans hope this shows just what is needed to catch up.
