Chelsea boss Thomas Tuchel is delighted with the impact of Thiago Silva.

The veteran centre-back also played for Tuchel at Paris-Saint Germain, and is a key part of the German's defense at Chelsea.

When asked about how Silva's game has evolved since their time together at PSG, Tuchel said the following during a press conference.

He stated: "Of course, the circumstances are different, it's a different club here. The rules and atmosphere are different, so that's normal.

"There's a special atmosphere at every club, that was the case at Paris Saint-Germain and it's the same here at Chelsea.

"There's a winning mentality here about showing your strength and playing as a top team with experienced players.

"Thiago Silva was very brave to make the decision to join the Premier League at his age, with his status at Paris Saint-Germain and to completely change his life.

"He's been fantastic since he arrived; it's the same story now, it's a pleasure to be his coach because he sets an example every day, he's very humble and professional and he's an exceptional player.

"We've had a back three in many games and he's excellent in the middle, he contributes so much with his experience. It's only a good thing because he's very reliable.

"He's the same person that he was, and I feel he was very brave to change his life towards the end of his career, that's very impressive."
