The Portuguese took the reins at Stamford Bridge in the summer and has impressed many with the way he has handled his initiation into English football.
Brazilian ace Ramires has improved dramatically under the former Porto boss and has heaped praise on his influence in Southwest London.
"I knew him from Portugal, I remember playing against Academica when he became their manager two seasons ago when I was with Benfica," Ramires told the club's official website.
"Having the opportunity to meet him here is fantastic because I admire the work he did in Porto immensely and the person he is as well means he is the best trainer I have ever had.
"He is always giving you strength and belief, supporting you and telling you what you need to do.
"He is absolutely fantastic, very intelligent and understands the game amazingly well."
