Cavani already used the 7, so the rules state that he has to keep it for the season.They haven’t though, they literally let Cavani take the 21 vacated by Dan James and Ronaldo took the spare 7.
We haven’t asked if Ronaldo can take an occupied number.
I’m afraid the tears will have to flow hard on this one.
It was occupied and they've given Utd an exemption to the rules.
