Manchester City striker Sergio Aguero is back in training having been sidelined since December with a knee injury.
Aguero, 26, took part in a team session on Thursday which also featured forward Edin Dzeko, who has also been out since last month, with a calf injury.
Argentine Aguero had scored 19 goals in 17 starts before suffering ligament damage against Everton on 6 December.
City's next match is at Everton on Saturday followed by Arsenal at home.
The match at Goodison Park could come too soon for Aguero, although reports suggest he could be back for the match against the Gunners.
City are expected to further boost their forward line with the signing of Swansea's Wilfried Bony for £30m in the coming days.
Aguero has earned widespread acclaim for his performances this season, with Pellegrini hailing the striker as "one of the best players in the world".
His highlights include scoring all four in a 4-1 rout of Tottenham on 18 October and a hat-trick in the 3-2 Champions League win over Bayern Munich on 25 November.
