Sergio Aguero suffered an apparent thigh injury during Manchester City's Premier League match at Manchester United on Sunday.

Pep Guardiola's side were trailing 1-0 to Anthony Martial's first-half opener when Aguero – who had a goal disallowed for offside shortly beforehand – made way in the 59th minute.

A member of City's medical staff was then seen applying an ice pack to the Argentina striker's right thigh.

Aguero's fitness now looks likely to be a cause for concern for Guardiola, as his side head into a busy period of the season – including their Champions League last-16 return clash against Real Madrid on March 17.
