John Obi Mikel is backing Chelsea teammate Yury Zhirkov to fill the void left by Ashley Cole’s injury.

Zhirkov appears the prime candidate to replace Cole at left-back.

“Ashley is going to big a loss for us because he is a very important player for this team,” Nigeria midfielder Mikel told chelseafc.com.

“But we have Yury, who can play in that position as well, and this is football, these things happen.

“We feel really bad that something like that happens to him at this time in the season, we don’t want it to happen to him at any time of the season, but with such important games coming up it’s going to be a big blow.”
