Vincent Kompany might not play until the final weeks of the season, Manuel Pellegrini revealed on Tuesday.

The Manchester City manager delivered a devastating update on the fitness of the captain, who has barely figured this season due to a calf injury.

Kompany had already been ruled out until late January after aggravating his calf during a comeback that lasted just nine minutes on Boxing Day.

Now Pellegrini has admitted that the Belgium international could be absent for far longer in what could have a huge impact on the title race.

Pressed at his media conference on Tuesday about when Kompany may return, Pellegrini said: “Its difficult to know. We are still trying to find out the reasons for so many injuries. Myself I’m not so sure, maybe the last part of the season.”

The central defender made his return on Boxing Day after being sidelined since 8 November 8. He appeared to over-stretch within seconds of replacing Nicolas Otamendi and tried to run the problem off but could not continue.

The Belgian international took to Facebook shortly after the game to reassure fans following his early substitution against Sunderland.

“Today was a bad day for me,” Kompany wrote. “My body feels invincible – the best it’s ever been – but I’m challenged by a number of small and local injuries. It leaves me more frustrated than with any of the ‘big’ injuries I’ve had but it’s a challenge that I will overcome.”

Meanwhile, Pellegrini confirmed on Tuesday that Wilfried Bony, Fernandinho, Eliaquim Mangala and Samir Nasri will also miss Wednesday night’s clash against Everton at Etihad Stadium.

However, David Silva and Yaya Toure return to the squad after missing the Norwich FA Cup tie.”“It was good to rest both of them as they’re in the squad list for tomorrow – we’ll see who will be in the XI but we have to play two games so close together so we’ll see,” Pellegrini explained. “Silva is 100% fit – maybe it’s a risk for him to play Wednesday to Saturday.

“Mangala tried to work yesterday with normality but he couldn’t. He had some pain still in his muscle – for him, it’s best to wait a bit more. It’s the same for Fernandinho and Bony. For Kompany and Nasri, it’s longer.”
