Wigan boss Roberto Martinez has sent a warning to Chelsea that the title is not yet theirs.

The Blues host the Latics at Stamford Bridge this weekend in the final weekend of the Premier League season and a win to the Londoners would hand them the 2009/10 Premiership.

But Martinez has reminded the Blues that his side has already inflicted defeat on them this season and that they should not expect an easy game on Sunday.

"We have beaten Chelsea once this season plus Arsenal and Liverpool, so we know we are capable of giving any team a game on our day," he said.

"We are not playing for Manchester United (who are second), we are playing for Wigan Athletic and for the good of football everywhere.

"It is a huge challenge - that would be the case for any team going to Stamford Bridge when Chelsea need a win to clinch the title. But we will prepare for it as well as we can and we will go there determined to do our best.

"How can you feel your season is already over when you are part of a unique occasion like this?

"The mood in the dressing room is that the players are all up for it. They are ready for one final push and have a belief they can make it difficult for Chelsea.

"Football is all about dreams and it is a fantastic dream to have, that you can decide who wins the league."
