The forward, who has scored eight goals in 10 games this season, is yet to sign a new contract at Stamford Bridge and has been linked with a move to Real Madrid.
Jose Mourinho insists he won't "celebrate like crazy" if his Manchester Utd side win at former club Chelsea this weekend.
United had a hard time of it before the worldwide break, enduring a four-match winless run across all competitions before a dramatic 3-2 win over struggling Newcastle United. I think I'd try to control myself and respect the stadium and the supporters that were my supporters and what was my stadium for many years.
"So I would think which stadium I am in, which public is in the stands but apart from that it is another match for me".
Sarri also claimed Manchester United had the best squad of talent in the Premier League. "I am 100 percent Manchester United [on Saturday], no more space than respect for the stadium and the fans".
Luke Shaw, Nemanja Matic and Marouane Fellaini were all ruled out of worldwide duty with their countries and the United manager has revealed a number of others have returned to Carrington with problems.

"We took from the Lowry Hotel, 75 minutes and UEFA were nice, the referee was nice to allow us to start the game five minutes later because we at least need half an hour to be prepared, but it was not a problem with the club organisation". "At the moment City is better as a team, but player-by-player they [United] are very strong".
"Then we came back and we were waiting for the boys to come back from their national teams".
Mourinho faces travelling to Chelsea with all of his available players after being hit with a number of injuries.
