Chelsea manager Maurizio Sarri feels his side need to sign new two players during the January transfer market.
He said: "I spoke with the club and the club knows very well my opinion".
On Fabregas, Sarri repeated his belief the midfielder should be allowed to go, adding: "I need a replacement, but I don't need a very important player like Cesc unhappy here".
"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".
Chelsea want to keep Hudson-Odoi but are conscious that he only has 18 months left on his current contract and has threatened not to extend his deal if Bayern's offer is rejected. 'Hopefully, we will see more of that.
Earlier this week, sources told ESPN FC that Chelsea were prepared to report Bayern to Federation Internationale de Football Association if evidence of an illegal approach to Hudson-Odoi or his representatives was found, having been angered by the club's public pursuit of the academy graduate.
"He is one of the best (young players) in Europe", Robben told beIN Sports.
The full-back appears to be getting better every week at the King Power Stadium and Chelsea have enjoyed transfer dealings with Leicester in the past, with N'Golo Kante proof of that.
"As you can understand very well, I cannot tell you where", he said.
Bookmakers believe there is a real chance that both William and Hudson-Odoi could leave. Bayern Munich are a big club and he's probably seen how well Jadon Sancho has done in Germany.
Willian is 2/1 with Ladbrokes to make the move to Barcelona.
