Chelsea boss Maurizio Sarri was reluctant to discuss Arsenal goalkeeper Petr Cech.
Arsenal keeper Cech, 36, who is due to retire at the end of the season, has been offered a job by Chelsea which could put him in a strange position in Baku next week.
Sarri said: “I don't like to speak about an Arsenal player because, at the moment, he is a professional player.
"He has to play for Arsenal until the end of June, so I want to respect the player and the club. And Arsenal.
"I don't want to speak about Cech in this moment."
