And the club are set to report the German giants to Federation Internationale de Football Association over the possible transfer of Callum Hudson-Odoi.
Bayern sporting director Hasan Salihamidzic admitted the club's interest in Hudson-Odoi on Wednesday, much to Chelsea's annoyance, with the Blues threatening to report the Germans to Federation Internationale de Football Association if there is any evidence of an illegal approach.
Maurizio Sarri has refused to comment on Chelsea's pursuit of GonzaloHiguain but says the club need two players during this month's transfer window.
Speaking ahead of Saturday's Premier League match with Newcastle, Sarri added: "As you know very well I am not involved in the market. Now he needs to improve in some movements without the ball, but he is working very well at the moment so I am very happy with the player and would like to have him in the future". "He does not get the number that people expect but as a centre-forward, and as a team player, I have a lot of admiration for him".
"He's a very interesting player that we really want to sign", Salihamidzic said.
Sarri said: "Of course, if Morata will go to another club we need a replacement. It's normal", Sarri said.
Maurizio Sarri has revealed his belief that Chelsea need to sign two players this January, but stopped short of confirming which positions he would be looking to strengthen.
The coach's options on the wing have improved with the return to fitness of Pedro and Willian, who on Thursday was the subject of reports that Barcelona had submitted an offer worth £50m to sign him, with Malcom heading the other way. "My opinion is important for the club, but I can not tell you my opinion". Lampard has admired Hudson-Odoi's performances from afar and hopes the England Under-19 worldwide is still a Chelsea player when the January transfer window closes.
