London, May 12 Chelsea's left-back star Ashley Cole has said that the Blues must toughen up against the top four.

Sunday's 4-1 romp at Arsenal was the club's first win against their big three rivals this season.

Chelsea have lost at home to the Gunners, twice to Liverpool and picked up just a point against champions-elect Manchester United.

Blues left-back Cole said: "That's where we've fallen down. If you want to win titles and trophies, you have to win against the teams about you.

"It has been hard and we struggled against the top teams. But against Arsenal we got it right. They didn't play as well as they can but we'll take it."

Chelsea are now likely to finish third, leaving the FA Cup final with Everton their sole shot at a pot. (ANI)
