Chelsea's performances have markedly improved since Marc Cucurella started playing an inverted role, shifting to midfield instead of keeping width on the left while the Blues have the ball.
At a press conference after the 5-0 win over West Ham, Mauricio Pochettino was asked about the change and why he did not make it at an earlier point.
"This role we can implement, in the future, but before that it was because we needed to have the belief, the confidence, the trust, the team needs to compete," replied Pochettino.
"In all the tactical evolution we have in our head, the coaching staff, we need to apply in the future. You cannot sit if you don’t have a chair, you have to build the chair first.
"In football, even if you don’t have a team, but you still expect to behave like a team.
"It’s like an engineer who is going to build a building, who says ‘I want to see so quickly the nice furniture and the flat’. But, first of all, we need to build the structure and everything.
"That is why sometimes we made a mistake when we changed the job of the people, the coaching staff, and also with young players we always say be careful with the way we change.
"Because the most important is to see in which moment we are, which type of team, all the things you need to establish clearly."
