'A new standard for Premier League performances' - reaction
Man City captain Vincent Kompany: "It's the same feeling as the first time and you can't describe it. It's amazing, such a difficult achievement and I'm proud of the team and everyone involved. This one differs in that we were consistent the whole season and we were able to play at the level we're expected to perform at.
"I'm buzzing, over the moon, so happy. I'm proud to be able to share this with all our fans, everybody who's been there to support us."
Chris Sutton, ex-Chelsea striker, on BBC Radio 5 live: "Manchester City have deserved it. Their brand of football this season has been scintillating.
"They've scored more goals and they have a brilliant manager. Their football on the eye has been superb and they've been streets ahead of everyone else.
"Old Trafford was a Theatre of Nightmares this afternoon. You'd think they'd back the derby win up with a strong performance. But they've handed the title to City on a platter."
Ian Wright, former England and Arsenal striker, on Match of the Day: "They have been magnificent. Guardiola has brought the right players. They have been scintillating all season and very much worthy champions.
"The goalkeeper was a major acquisition. Kyle Walker has been magnificent too and I'm delighted for him, but the players that were already there have improved too. That's what Guardiola needs to get praise for.
"City are already thinking about making sure they can retain it next season and do better in the Champions League."
Leon Osman, ex-Everton midfielder, on BBC Radio 5 live: "They definitely deserved the title. They've been fantastic this season, right from the start. Their performances out of the blocks in the first 10 games were incredible and they really set the tone for the season.
"[Winning at] Chelsea - a massive result away at the champions - early in the season really did put a marker down for everyone else to say we're the team to beat. They looked at one point like they were going to go unbeaten.
"I do think they've set a new standard for Premier League performances and what you expect from title winners moving forward."
Shaun Goater, ex-Man City striker, speaking to BBC Sport: "For me, it's by far the best City team I've seen. The way and the style they've gone about it is truly total football.
"City have done it in amazing style. That's what's been so beautiful - the way City have won this league."
Man City chief executive officer Ferran Soriano: "Winning the Premier League again is a great honour for Manchester City. We are delighted to have done so providing our supporters with some very exciting and unforgettable moments.
"We are committed to playing beautiful football and we are proud to have done it so brilliantly this season. For all Manchester City supporters, at home and globally, it is time to celebrate, acknowledge our friendship and enjoy our passion together."
Martin Keown, former England and Arsenal defender, on Match of the Day: "Last year Antonio Conte was the pragmatic manager but this year Guardiola had the flare.
"They have been in the shadow of Manchester United for so many years but they are well and truly out of that shadow now. Look at how much better City's players are now than at the start of the season. They just keep getting better and better.
"Guardiola is a serial winner of trophies so you go up another level. He made the necessary changes - he had the money to spend of course - but he spent it wisely and he set the tone. The players clearly know what they are doing and it's a canvas for success."
'They paint beautiful football' - how City have been described this season
Match of the Day commentator Jonathan Pearce described Manchester City as an "irresistible force" and one of "the best the Premier League has ever seen".
Midfielder Kevin de Bruyne heaped praise on his own team, saying: "The way we play is probably one of the best in the world."
Former Arsenal defender Keown described City's players as "artists" who "paint beautiful football for us each and every week".
Chelsea manager Antonio Conte said he admired how they "found the right way to be strong for a long time".
Five key games in City's title march
Watford 0-6 Manchester City (16 September 2017)
A statement of intent from Manchester City. They
scored six without reply against Watford after putting five goals past Liverpool the previous match. The result sent City to the top of the table, where they have stayed.
Manchester City 2-1 Southampton (29 November 2017)
Just as Southampton looked to have held on for a hard-fought draw, Raheem Sterling curled in a winner
in the 96th minute. The win came in a period which saw City also beat Huddersfield and West Ham by the same scoreline through late goals.
Manchester City 3-1 Newcastle United (20 January 2018)
Manchester City 2-3 Manchester United (7 April 2018)
City would have sealed the earliest Premier League title with victory on derby day. They were 2-0 up after 30 minutes, but spurned numerous opportunities to increase their advantage - and were punished as United staged a remarkable second-half comeback to
win 3-2 at the Etihad.
Manchester City 1-3 Tottenham (14 April 2018)
After three losses in a week - twice to Liverpool and the Manchester derby - Guardiola's side bounced back with an impressive
victory over Tottenham at Wembley, putting themselves on the brink of title glory.
