Chelsea boss Frank Lampard says new signing Thiago Silva has already made an impact around the club.
Silva took part in his first training session as a Chelsea player on Thursday after having extra time off following PSG's Champions League final defeat by Bayern Munich.
Lampard said: "Certainly a leader. He'll bring that with him by nature.
"He doesn't speak the language that great at the moment but we'll work on that.
"By presence, by attitude in training and quality of the player, he commands respect and it is great having him around. That's all you can ask for as a coach."
It remains to be seen whether Lampard will play the 35-year-old against Premier League champions Liverpool on Sunday.
