That was under Jose and was a shitshow as Martial wasn't asked and wasn't fine with it.Wow I didn't think it was that strict where a previous players shirt number stopped another player getting it - especially since I saw Mattial to Zlatan.
Ole's been mostly about bringing everyone together and pulling in the right direction hence one of the early things he did was give Martial the number 9 back.
I don't expect Varane to get number 4, but if anyone is to get an existing number, that'd be the most likely one with Jones having not played for over a year.
