Chelsea’s defence have been solid since Thomas Tuchel became Chelsea boss in January.
Explaining what makes Chelsea’s defence difficult to penetrate, Chelsea goalkeeper Edouard Mendy told the official Chelsea website: “The defence works as a team. It is not just down to me or the defenders in front of me.
“It is defensive teamwork that starts with the strikers and finishes with me. We see very well when we press that we are very active when we recover very high balls.
“And, when the opponent has possession, we see that we are a difficult block to get through because the whole line moves very well and it’s very difficult to get through our block.”
