And Ranieri said ""I think that Damien is one of the very important players at the start of the season. When he takes the ball, something special happens and this is important for us.
"He's also a nice guy and is always laughing and joking, but then he's Irish! He's fantastic and has adapted very well, just like everybody else.
"Against his old club though, I think the most important thing is that he plays for Chelsea and not that he wants to score. The big champions always think about the team.
"In the second half against MSK Zilina, when Emmanuel Petit came on, he was fantastic because he didn't want to show something special, he just played football like he knows how.
"That was very important for him. Damien must also just play how he is now used to playing for Chelsea.''
