Frank Lampard declined to comment about Bayer Leverkusen attacking midfielder Kai Havertz, who wants to leave the club this summer and has been strongly linked with Chelsea.
Lampard said: "I'm not talking about Kai Havertz. I've said before, he's a player of another team. Looking at the game tomorrow, which is so huge for this club, the last thing I want to do is talk about players for other teams."
