Manchester City midfielder Fernandinho faces a knee scan today.
He will undergo scans on Thursday after twisting his knee in Manchester City's 2-0 derby win.
The Brazilian was substituted early in the second half and is waiting to learn the extent of the injury.
He said: “When I blocked a shot from Paul (Pogba) I felt my knee. It twisted a little bit. I could continue playing, but I came off. That's what it is.
“We are going to make the scan and we will see. I will talk to the doctor and he will make the best decision for everybody."
