Antonio Conte coached Swansea City striker Fernando Llorente for one season at Juventus before leaving to take charge of the Italian national team in 2012.
Conte is aware Llorente will be a threat to Chelsea and he expects the players to pay attention tomorrow.
“I know him very well because Fernando played with me in Juventus and we won (the title) together,” Conte said.
“He is a really good player, good footballer and I have great admiration for him the player and also the man because he is a great man.
“It is a pleasure for me to see him tomorrow. I wish for him the best but after this game.
“Was I interested in signing him in January? This is the past and it is not right to talk about the past and be focused on the present.
“I have great admiration because he is a great player. We must pay great attention tomorrow.”
