Chelsea boss Graham Potter says they're wary facing Diego Costa with Wolves this weekend.

Costa returns to Stamford Bridge to face his former club.

Potter said: "I've got a respect for him, for his career, what he's achieve. He's a Wolves player and he's going to come and be ready to play. Everyone at this club knows how good he's been and I've followed his career from afar and have huge respect for him and what he's achieved as a player. Like I said, lots of talented players at Wolves, especially the forward line. A lot of attacking players there that can hurt you, so we have to be ready."

On managerless Wolves, he continued: "It's one of those things, I have no idea. My focus is on us on making sure we're ready to play. We haven't got a lot of time to prepare. You can't control the opposition's situation. You see the games in the Premier League, the margins are so small. They've been in games that they've narrowly lost. Historically it's a challenge playing Wolves, we have to be recovered and ready and positive and looking forward to the match."
