Chelsea midfielder John Obi Mikel says Arsenal don't like to get physical.
Chelsea are set to face Stoke City and Mikel says the contrast between the Potters and Arsenal couldn't be greater.
He told chelseafc.com: "We played very physically against Arsenal last year and they don't like it, but Stoke relish it, so we have to make our extra quality on the ball count again this time.
"It will be a very difficult game, trust me, with the long throws and the ball in the air, someone like Ricardo Fuller up front, they are the toughest opponents.
"They kick the ball up, you think you are going to win it and then they are there and you're beaten, you have to be aware all the time.:
