Cheikhou Kouyate is convinced West Ham United can challenge Chelsea on Boxing Day.

Kouyate believes his side have the ability to overcome Jose Mourinho's men.

"We've nothing to lose at Chelsea because we're playing the best team in the league, in the country," he told the club's official website.

"They're first and it's no fluke. We'll go there with nothing to lose and without fear. If we're fearful, we're better off staying at home!

"This is football and we shouldn't forget it, we've got to enjoy it and we're going there to do just that."
