Kevin De Bruyne scored the only goal of the game on 70 minutes, producing a trademark long-range strike to break the Blues' back line and haunt his old club.

Guardiola and co were made to work for their result, with Thomas Tuchel 's side defending resiliently for the most part.

They came close through Jack Grealish in the first half and were almost punished shortly after the break when Romelu Lukaku fluffed a chance.

Many now believe the title is wrapped up but Citizens hero De Bruyne poured cold water on the notion of the race being won.

"We knew if win today we make the gap bigger on them on the title," the Belgian told BT Sport.

"We don't have to look at that, we've been in this situation before where we are points ahead but even I think in the second year we were the same points behind and a lot of things can change and the momentum can swing very quickly.

"I think the team was focused on the job they needed to do – that’s the only thing we can really do."

On the staggering 13-point gap, De Bruyne added: " It is very hard because obviously I think they [title rivals] need to be almost perfect but there's another team who is dangling there so just keep the momentum, keep doing what we need to do and try to win each game by each game.

Post-match, Tuchel claimed his team deserved a draw, telling BT Sport: "The result, yes [is disappointing], but this can happen. I think we deserved a draw, I think we defended very, very well and did not allow any big chances.

"One in the first half from a mistake from us but we were not under so much pressure that it was clear they would score. Performance wise this is okay, given that we had to change our back three again.

Guardiola got the better for Tuchel for the second time this season

"Defensive wise I am absolutely okay with that performance, we deserved a draw, it would have been a fair result, but we don’t have it. We have won games like this against City and that feels very different but that is the way it is.

"We had eight or nine offensive transitions and zero touches in the box. That was a big problem today. Offensive wise the performance of the front players was simply a lack of position, a lack of timing and a lack of composure. We lost too many balls too easy and that was a big problem in our game today."
