Charlie Adam has insisted that Stoke City are confident of causing an upset when they make the trip to Stamford Bridge to take on Chelsea this Saturday.

Chelsea will be looking to take another step towards clinching the Premier League title as the two sides return from the winter break, but Adam believes that there is no need to fear Jose Mourinho's team.

"It's going to be a tough game. It's not just about [Diego] Costa, they have [Cesc] Fabregas, [Eden] Hazard, Oscar - a lot of good players - and it is a difficult place to go, especially when they are playing with a lot of confidence," the Scottish midfielder told reporters.

"But hopefully we can go there and cause them problems.

"You can find chinks in the armour. We always make a point before the games of looking for the weaknesses in teams and what we can exploit. Hopefully we can pick out some points."

Stoke could move up to eighth in the table with a victory on Saturday.
