Manchester City are sweating for their Champions League future and sweating on the fitness of Ruben Dias after the defender had to come off against Paris Saint-Germain.

Dias was replaced at the break against the French champions and while he was on a yellow card it was confirmed by Pep Guardiola after the match that the change was enforced. The Portugal defender only returned to the squad a week ago but could not go back out for the second half in Paris.

"He didn't feel good," said Guardiola. "He asked to be replaced because he didn't feel good. I don't think [that he will be out for a long time] but he said he could not play in the second half."

Guardiola's other half-time change looked to be a masterstroke and Jack Grealish scored and set up a goal within 10 minutes of coming off the bench. However, the Blues promptly threw away their lead and Ilkay Gundogan, James McAtee and John Stones were all unable to stop the momentum of the home side when they came on.

City's boss gave credit to PSG for the force in which they worked their way back into the match. However, the way in which City were bulldozed through again - this was ninth game this season out of 33 where they have given away a lead to either draw or lose - is a worry that refuses to go away.

"To defend we have to play and we could not," said Guardiola. "Keep the ball, make an extra pass.

"I give credit to PSG, how aggressive they were. PSG felt us when we scored. Then the momentum with the crowd and what they're playing for. It’s normal.

"We could not have the ball. I tried Gundo and Macca, with Jack, to keep the ball but we couldn’t do it."
