I am not entirely sure if Chelsea would even care, Mudryk isn't really a must for them, they are winning without him easily, so it doesn't feel like they would care. They famously have a lot of players anyways, that was a talk during the summer, they have like 40+ players or something, probably less now but still a lot, so losing one of them won't matter.
Chelsea will not actually missed Mykhailo Mudryk, he is not a key player in the EPL and this is among the reason many have been amazed about his doping scandal. There are other players to fill his position and we may likely never even noticed that he's no longer on the team.
If this was Cole Palmer or Jackson then we would be seeing them in shambles without a doubt, but Mudryk doesn't really feel like he is important enough to care. They would just use that as a reason to unload him and sell him to another team, that has to be the most important part. I believe we are going to end up with a lot more and that has to change on the long run.
Cole Palmer and Jackson are key players that will often be felt especially Cole Palmer but in the over all Chelsea squad I think the most important player now is Moisés Caicedo who has been the very best Dm in the EPL this season.
