City were confirmed as title winners for the third time in four seasons on Tuesday after Manchester United's defeat to Leicester left us with an unassailable 10-point lead with three games of the season remaining.
It means we have now collected 10 of the last 15 major trophies available in English football.

"What happened this season, with COVID, the restrictions, we couldn't enjoy normal life, like everyone in the world, of course. But it makes it even more difficult," he said.
"To come back from last season's Champions League, no holidays, injuries, COVID...and what this team has done has been incredible.
"The players, coach, football club, fans and there is a togetherness that makes us special."
