Reports stated that Victor Boniface failed medical test which means it was nothing except for the knee injuries that was the reason for the failure of his deal move to AX Milan. The ACL injuries was what made Milan management changed their interest on Boniface. Maybe it will interest you all to know that he sustained the injury in his time at Bodo/Glimt before signing for Leverkusen and since he been playing so well after a successful surgery but Milan management thinks otherwise after discovering of his one time ACL injury as they fear it could affect his performance.
Boniface is upset about the transfer being cancelled, he was probably interested in playing in Milan, but I think Bayer is no worse. I understood that the whole problem was in an old knee injury and at the moment everything is fine with his knee, but apparently Milan's doctors decided that it was not worth the risk because they thought that it could be his weak point. Maybe they are right to some extent, it is better to find another forward than to be wrong and get an injured forward. And Milan will now need a forward again, and the season has already started.
I was wondering why the much interest in joining Milan at this time when Milan isn't anywhere in the European football competitions and not actually doing great in their domestic league either, meanwhile Bayer Leverkusen where he plays for are having it much better than Milan in European football competitions, they're even playing in the UCL and one of the top teams in their domestic league. Perhaps Victor Boniface don't want to play under Erik Ten Hag hence his interest to Milan.
