Chelsea fullback Ben Chilwell praised manager Graham Potter for reacting during their 1-1 draw with Manchester United.

Potter's decision to swap Marc Cucurella for Mateo Kovacic and add an extra body in midfield came at a time when United were swarming all over the hosts.

As the closest operator to the dugout during the first period, Chilwell was the man on hand to receive instructions from his manager and revealed the thinking behind the changes.

"In the first 30 minutes, they were really on top of us and dominated us a little bit so we made a tactical change," he told the club's website. "I was the closest player to him [Potter] so he pulled me and said we were going to go to a back four.

"Credit to him and to us because we adapted with it well, especially as it wasn't even half-time but during the first half. We went with the diamond in midfield where we overloaded them and grew into the game, especially in the second half when we controlled the game a lot more.

"The formation change was really positive for us and it gave us a lot more possession so it was a positive tactical change and we dealt with it well, which the manager expects. The fans got behind us, we grew in confidence and then got the goal. We hoped that would be it but it wasn't to be."

Chilwell also had words of praise for the ice-cool Jorginho, who was forced to wait for several minutes before dispatching his spot-kick, and reflections on extending our undefeated run under Potter to eight matches.

"Jorgi is the coolest guy in the room, especially when it comes to penalties and I think it's something you're either born with or not,' he added. 'You've seen it time and time again. His Chelsea record with penalties is magnificent and again he delivered.

"We've got full confidence in him when he steps up to take the penalty and the way he does it is brilliant so long may it continue that he performs for us in that respect.

"We've got a really good mentality and we're very confident going into games at the moment. Even if you look at the first 30 minutes today, we defended well, we were together as a unit and solid.

"I think that's something we've brought on leaps and bounds since the manager came in - the defensive togetherness, we're keeping clean sheets and we nearly kept another one today. We just need to keep building on that, keep that defensive unit strong as a whole team and then build from there."
