The Premier League match between Chelsea and Wolves is on Saturday, and head coach Graham Potter has given his assessment as Diego Costa prepares to make his return to Stamford Bridge.

The Blues have had a great week and hope to cap it off in style this weekend when they host Wolves.
Conor Gallagher’s late wondergoal in the 90th minute gave Potter his first victory as head coach last Saturday’s 2-1 victory over Crystal Palace.
Chelsea needed a big win and performance against AC Milan in midweek after a sloppy start to their Champions League campaign.
After losing to Dinamo Zagreb and drawing to Red Bull Salzburg, the Blues were bottom of the group heading into this one, but they cruised to a 3-0 win over the Italian giants.
Wesley Fofana, Pierre-Emerick Aubameyang, and Reece James scored to secure the three points.
The Midlands team made the announcement that Bruno Lage had been fired earlier this week due to a sluggish start to the season. Steve Davis and James Collins will now serve as the team’s leaders for the match on Saturday.
The potential for the west London team to move into the top four is presented by Brighton & Hove Albion, who don’t play until the evening kickoff against Tottenham.
In his pre-game press conference on Friday afternoon, Potter answered questions from the media and discussed the opponent.
He stated: “A lot of talented players, can’t control others situations (managerial sacking). We expect a tough game so we have to be ready and positive.”
Wolves currently sit in 18th place and largely contributing to their downfall this season has been the struggle to score.
When asked about the attacker’s return to Stamford Bridge, Potter responded: “We have a lot of respect for what he has achieved.
“He will come ready to play. Everybody knows at the club how good he’s been. He’s one of lots of talented players at Wolves that can hurt you, so we have to be ready.”
He continued: “I’m not sure, I hope so (good reception). Always when players achieve something at the club you hope so. But that’s not for me to decide.”
The Spaniard came off the bench against West Ham United and is expected to play against Chelsea.
His presence will almost certainly make the game more heated, and Chelsea fans are well aware of what Costa is capable of.
