Manchester City  boss Manuel Pellegrini  has revealed that midfielder David Silva  is set to be sidelined for up to a month with a calf injury.The 27-year-old was one of two players, including team-mate Fernandinho, who suffered injuries during their club’s 5-2 win over CSKA Moscow in the Champions League on Tuesday.
Now the Spain winger, who was forced to cancel a promotional event on Wednesday in order to undergo tests, has been confirmed as an absentee for up to four weeks."Obviously we have another day before we make any decisions but David Silva, Richard Wright, Stevan Jovetic and Vincent Kompany will miss the Sunderland game," said Pellegrini at a press conference."As I say we have some more time but we will have to wait and see. Silva has a problem with his calf so he could miss three or four weeks."However Fernandinho, who was replaced at half-time in the same game for James Milner, is expected to face a fitness test ahead of their weekend trip to Sunderland, along with central defender Matija Nastasic.He continued: "Fernandinho and Matija Nastasic have slight problems but he could possibly be fit for Sunday."Silva's absence could see him miss up to seven games including a league clash with Tottenham on 24 November and a visit to Bayern Munich in one of two Champions League ties.
