Chelsea new boy Mykhailo Mudryk has posted a cryptic message on his Instagram account.

The Blues winger came in for some criticism after his indifferent display in the Champions League against Borussia Dortmund.

Despite having a lot of possession and creating chances, the Blues lost the first leg of their round of 16 tie 1-0.

Mudryk had a great chance to score, but did not, and was criticized by club legend Joe Cole.

On his Instagram account, Mudryk wrote: "I am here to show what a Ukrainian man is. A warrior. A warrior loves challenges.

"A warrior is born to overcome challenges. Nothing obsesses so much, the man who put everything on the line, as a victory. A warrior can on his way lose battles, but in the end the warrior wins."
