Reece James was out for three months and made a comeback this weekend against Burnley.
Manager Thomas Tuchel has credited the 22-year old right-back for his recent return from recovery who looked so sharp in training and in the Burnley game.
He scored the opener at Turf Moor and an assist to Kai Havertz’s second of the game.
“We missed him for such a long time that you get used to it,” admitted Tuchel.
“It was nine weeks and in this time we had something like 25 matches so we were constantly trying to find solutions and we did as a team.
“We managed to win games and even titles in this period but once he’s back and plays three times, today the first time from the beginning, you see what you missed.
“It’s such huge quality and very impressive how decisive he is in training and now even in the games.
“These positions are very important when you play with this structure and it’s the same on the left side so its puts things into perspective when you see what we missed and I’m very happy that he came back like this.”
