Manchester City Manager Manuel Pellegrini gave an injury update in advance of the Blues trip to West Ham on Saturday.
"Fernandinho is fit, he's worked with the squad for the last two games. Mangala, Bony, Kolarov, Kompany and Nasri are out.
"Vincent is seeing different specialists to try to learn more about his injury. He will start working, I hope, next week, but we will see.
"Bony maybe has an injury which is longer than we supposed. I hope next Monday he will start working with the squad.
"Aleks has a muscle injury in his calf - not very big. I hope at the end of the next week he'll be working with the squad."
Bony's injury of course means that if the Blues play a 4-4-2, Kelechi Iheanacho who has quickly emerged as a fan favorite might start. The 19-year-old has been a revelation this season scoring a goal approximately every 70 minutes he is on the pitch. Gaël Clichy will get the start in place of Kolarov and Fernandinho likely will replace Fernando in the lineup.
