Gonzalo Higuain will not fly out to London until at least Tuesday, as before joining Chelsea, Milan must secure his replacement Krzysztof Piatek.
There had been reports in the English media today that Pipita was on his way for a medical and would be registered ahead of the showdown with Tottenham next week.
However, Milan will not let him leave until they have his replacement under lock and key.
It’s bad news for Chelsea, as talks with Genoa for Piatek have been adjourned to Tuesday.
A deal is still imminent for €35m plus bonuses and midfielder Alen Halilovic, but won’t be completed for several more days.
Higuain is technically owned by Juventus, who sent him to Milan on loan over the summer for €18m with option to buy for another €36m.
Those terms will be handed over to Chelsea, with the additional agreement they can extend the loan by another 12 months.
