Chelsea wing-back Victor Moses admits he's struggled to perform in Russia's harsh winter conditions.

Moses is currently on-loan to the end of the season with Spartak Moscow.

After being sent off in Spartak's Russian Cup defeat to Dynamo, he said, "I have never played in such weather.

"Before that, the record was minus one, it seems. This is the problem: in such cold weather you don't really feel the ball. I tried to act useful, but the field was very difficult.

"I want to forget such days as soon as possible.
