"I think we deserved to win. The players worked very well, prepared very well the game. This morning, yesterday, all days in the last week and the qualities of the players are very clear.
"I'm happy for the spirit of the players. I think we have to change the last part of the history of our club. I would like to follow in this way."
On fight spiriting: "Football is the quality of the play, the quality of the players, for sure, but it is a competition. It is a fight. You have to run, you have to fight, you have to arrive first to the second ball. You have to win the duels and we did."
On tactics: "We knew Chelsea play very well, they have clear organisation, clear structure on the pitch. We prepared our players with two midfielders and James Maddison with freedom, where he smells the right position."
On James Maddison injury: "He played very well while he was on the pitch then [Conor] Gallagher played with different characteristics. Different style but he played very well.
"James is a different player. He feels football, he understands football. It is easier for me when you have a player of his talent.
"I think it is not a big problem. We have to see."
On Mathys Tel: "Mathys needs to play to understand football, become calmer but he is a big talent."
On confidence after a big win: "I think it is important for the players to belief more in themselves because their qualities are very high. We are happy for the fans, first of all, because we know what it means to beat Chelsea and for the club as well.
"In the last years they suffered, like the fans, they believe in this project, in this group and I'm happy for them."
