Chelsea ace Frank Lampard insists they can challenge for the title this season.

Sunday's come-from-behind 2-1 win at Everton moved them within four points of second-placed Manchester City and 11 behind leaders Manchester United, and they have a game in hand over both sides.

"Of course we can still win the league, it is possible," said the England midfielder, who will be on his way out of Stamford Bridge by the summer unless a new deal can be agreed to keep him.

"If we concentrate on ourselves, win our games, put a long run together and we can put pressure on Man United, who knows?

"We have to be positive and the big change going into games is attitude with a desire not only to pass and move the ball but to get close and work for your team-mates.

"When we have that we can do what we want we need to carry on that starting with QPR."
