It seems that Chelsea has learnt how to win by all means, either by crooks or hard work.
If Chelsea will continue to win this way, they are going to be threat to many teams.
But now it seems that Chelsea has an issue, Palmer is out and today Delap is injured and infact, Chelsea wanted Jackson back to fill the space but it seems that Jackson has already sealed his fate and already made up his mind to be in Germany with the Bundesliga giant.
So, if Chelsea doesn't play their game well, they might be having attacking issues and it will affect them especially when champions league sets in and they will be having many matches to play.
I read on Ben Jacob page on X that nothing has been signed yet, he only went for medical and documents hasn't been exchanged between clubs yet. He's still contracted to Chelsea and only them can decide on what to do and if they want him back, he can't do otherwise afterall he was going on a loan.
Unless he wants to be like Isak and Wissa and run away and probably get fined but all of that doesn't make sense, in his best interest he needs to return and fight for his place.
