More importantly, though, it means Pep Guardiola's City team can not now be caught at the top of the table, thus handing the Catalan coach his first Premier League crown in just his second year in English football. Combining speed, guile, power and more speed, it has blown away opponents and redefined what anyone thought was possible in the English game. They were the right ones and the ones we believed in, I'm sure there are differences to how we play today compared to Bayern (Munich) and Barcelona, we survive and live by the strength of the team.
But he was rapt in conversation with Kyle Walker when leaving the field and in the midst of it began gesturing animatedly towards the area of the field the full back had just spent 45 minutes occupying.

Jose Mourinho's 2015 Chelsea side won the league handsomely but could only finish 10th the following campaign. That theory has been wholly debunked.
Backed by free-spending Abu Dhabi owners, Guardiola has had plenty of talent to work with. Instead, City imposed their will again in the second period as Raheem Sterling grabbed a third and was still angry at himself for missing a host of other opportunities to make the scoreline even more convincing.

Guardiola, who failed to land a trophy in his first season in charge at The Etihad, opened his account by winning the League Cup in February against Arsenal. I thought we did the counter attacks really well, broke things up and created some chances. "After what this club has done in the last ten years, in terms of creating facilities and making it bigger, it will happen".
"You have to gamble every time".
They are eight points adrift of the Premier League record for points in a season, Chelsea's 95 in 2004-05, and can become the first team to break the 100-point barrier, with a total of 102 possible from their remaining five matches.
Guardiola sounded like a man who will be there when it does.
