Sergio Agüero will return to the Manchester City squad for Wednesday evening's FA Cup third-round replay against Blackburn Rovers at the Etihad Stadium following a calf problem, though Yaya Touré and David Silva are both out injured.

Agüero, 25, returned to training this week after recovering from a calf injury that has ruled him out since the 6-3 Premier League win over Arsenal on 14 December.

However, Manuel Pellegrini indicated that Samir Nasri's knee injury may keep him out for less than the eight weeks the Frenchman predicted on Monday, with the manager stating that his prolonged absence would not affect City's transfer policy on the current window.

Of Nasri, the Chilean said: "A very important player for us. He was also playing in a very good moment so we hope he can come back as soon as possible but I think less than six or seven weeks will be difficult.

"No, it has not changed our philosophy. We know exactly what we are going to do in the transfer window."

While Agüero is likely to be a substitute for Rovers' visit, Touré and Silva have minor problems and should be fit for Cardiff City's visit on Saturday.

The striker John Guidetti, meanwhile, has joined Stoke City on loan.
