Chelsea defender Andreas Christensen says there'll be no underestimating Arsenal on Sunday.
Christensen believes Arsenal will be "difficult" opponents for champions Chelsea this weekend despite the Gunners' troubles on the road this term.
Asked about the London derby, the 21-year-old told talkSPORT: "We are looking forward to that, it's come quickly. This month, we don't have too much time off.
"We have to work hard in the training ground and I think everyone is looking forward to the week coming.
"You can't look at that [Arsenal's two away losses this season]. You just look at the players they have and the team they got.
"We know how difficult it's going to be."
