Such news like Chelsea will make an offer for Osimhen in January has been refuted. However it was already meaningless honestly. Because they already have Nkunku even though he is injured. When he recovers they would go on with him and then decide whether there is a need for another striker. But of course we don't know when Nkunku will recover for now. 

I think Chelsea should sign a better goalkeeper rather than signing a striker now. I don't like Robert Sanchez now. He isn't a player who is at Chelsea's level at the moment. Kepa is also not coming back at least until the end of the season and I doubt his future at Chelsea later as well.
