The Russian winger has struggled to force his way into the Blues line-up since joining from CSKA Moscow a year ago and says he will be forced to leave Stamford Bridge if that doesn't change.
"I'll certainly get a chance in the next few months and I'll try to use it," he said.
"Then, in the winter, everything will probably depend on whether I get a chance and how I use it.
"You can be on the bench for a long time. But I will definitely get a chance. You want to be on the pitch to help."
