Chelsea boss Graham Potter has no doubts about Pierre-Emerick Aubameyang facing former club Arsenal on Sunday.

The Blues host Arsenal with Aubameyang to face his former club for the first since leaving in January for Barcelona.

Potter said, "It's a London derby, two good teams I think.

"Arsenal are doing really well and the history makes it an interesting one for Auba.

"But the past is the past as we're concerned.

"I don't think we should make it about him. He is an important part of the team for us but it takes everybody, not just one person.

"I think he's looking forward to the game, excited for it. He's been pretty normal I say, quite a quiet guy."

On their recent record against Arsenal, he added: "Recently, it hasn't gone so well if I'm not mistaken, so we have to do better there.

"It's a London derby and anything can happen in the game.

"We want to be positive, play well and get the crowd involved in the game."
