Chelsea boss Graham Potter was pleased with Benoit Badiashile's debut in victory over Crystal Palace.
The former AS Monaco defender played from the start for the 1-0 win.
Potter said, “I thought Benoit did well, really well. It was a good game for him. Kalidou Koulibaly has had a lot of football recently and with the turnaround from Thursday night to today, that was a consideration for us. You can see his quality.
"He passes the ball well, when he needed to head it out he did, he's adapting to the Premier League and that will take time because he's a young player. I think he'll get better and better but the first game was very positive."
On the signing of Mykhaylo Mudryk, Potter added: “You're never surprised in the transfer window because things happen when you don't expect them to happen. In terms of what he brings, he's a player with a big future, exciting, one vs one, he's very direct, he attacks the back-line, can go into wide areas but also affects the goal. A really exciting player and I think our supporters will really like him."
