Petr Cech will remain “professional” even though he could make an immediate return to Chelsea after the Europa League final.
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.
It will be desperately disappointing for Cech that news of his switch has come out now but Arsenal boss Unai Emery is set to stick with him ahead of Bernd Leno.
But Chelsea boss Maurizio Sarri insisted that it would not be difficult for Cech to face his potential future employers.
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.”
Sarri did express his disappointment about Ruben Loftus-Cheek suffering a serious Achilles injury on Chelsea’s end-of-season game in Boston.
England midfielder Loftus-Cheek would have been a certain starter in Baku and Sarri had been publicly outspoken against the friendly.
Sarri said: “In Boston, the pitch was really not very good. But in an injury like that, there isn’t only one reason. Probably there are a lot of reasons. So we cannot say the only reason is the pitch, of course.
“You know very well my opinion about Loftus. Loftus was able to become a very important player for us, especially in an open match. In the space, he’s really very useful for us. So I’m disappointed.
“But it’s useless to continue to speak about him. I am sure he will be able to return stronger than in the past. He will become, for sure, one of the best midfielders in Europe. I don’t know the timing because it’s very difficult to say now: four months, five months.
“Then we need to consider the timing is different… probably he will be able to have training with the group after five months, but then he needs to be able to play at 100% of his possibilities, and that’s different. I don’t now the timing, but four to six months.”
