Manchester City boss Manuel Pellegrini will test James Milner in striker's role during training this week.
City face three matches this month without a fit striker after Edin Dzeko injured his calf before kick-off at Leicester and joined Sergio Aguero and Stevan Jovetic on the casualty list.
"We will work this week with the players to see who can play best in that position. It can be Silva, it can be Nasri, it can be Milner," said Pellegrini.
"We must decide which is the best one. I always said James is a very useful player for the squad. At some moments he wants to play more but wherever he plays he is important. That is why we've kept him here.
"Pozo is not a striker. We must try to find another way to play because our strikers will be out for at least one month more."
