Graham Potter started the game against Manchester United with a 3-4-3 formation, with Jorginho and Ruben Loftus-Cheek playing in a double pivot role.

However, with United bossing the game in midfield, Potter decided to introduce Mateo Kovacic in midfield, and the Croatian helped bring balance to Chelsea’s play, as Potter switched to a 4-3-1-2 system.

Kovacic had a very good game, and one would wonder why he didn’t start the game.

According to Potter, Kovacic has been nursing a knee, and he’s only being careful with the Croatian.

Graham Potter said: “He’s been nursing a knee for all of the season, pretty much. And then you look at the schedule and it’s suddenly games Wednesday and Saturday, it’s impossible for him to start all the games.

“We’d planned for him to have less time than he has, but things have conspired so he’s been on the pitch.

“We know his quality, but at the same time you also need to understand the player’s situation as well.”
