Manchester City star Sergio Aguero returned from injury overweight.

That is the opinion of Manchester United legend Roy Keane, who was on television as part of his duties as a pundit.

Aguero has only played three times since the start of the season. The 32-year-old is one of only two striker options for manager Pep Guardiola this term.

He did not play against Liverpool on Sunday in a 1-1 draw.

"My issue with Aguero when he came back was he looked overweight. God knows what size shorts he was wearing but he looked really heavy," Keane told Sky Sports.

"Sometimes you can be out injured, come back and hit the ground running, [I don't agree with] this idea that players need two to three months to get back up to speed.

"But I was really worried when he came back as he looked really, really heavy."
