Manchester City's all-time leading scorer Sergio Aguero had his participation in the Manchester derby cut short by a thigh injury.
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.
The game continued at a frenetic pace but the reigning champions could not find an equaliser in the absence of their striker. That means that Liverpool now only need six points to win their 19th English top-flight title.
