Juan Mata admits Chelsea face a battle to finish in the top four.

A hat-trick of 1-1 draws has put the Blues' top four spot back in jeopardy.

Mata said: "It is going to be very difficult because there are lot of teams and they are having very good seasons, like Arsenal, like Tottenham, like Liverpool, so we have to fight.

"Our next game is another that we have to win but Aston Villa is a very good team.

"We wanted to achieve the six points in our two home games but against Fulham we got one, and we hope to win three points against Aston Villa."
