IMO, Jose showed too much deference to Ibra when he stripped the shirt number from Martial, yes no one is entitled to anything except for respect, and Jose disrespected Martial in that case, at first he asked him if he is okay with giving up the shirt number, Martial said no, Jose should've left it at that, if we believe what we are told in the media, Ole asked Cavani to give up the No.7 shirt to Ronaldo, and Cavani agreed to that request, I am not giving credit to Ole or anything here, it's the common sense to do in terms respecting those around you, whether they are big name player or a youngster, Jose didn't show any respect to Martial.
As for his other comments, well, let's hope his injuries are behind him, he needs to come good this year, Ten Hag will definitely give him opportunities and play him in his preferred position as a striker, he had a good pre-season but was injured against A.Madrid and then against Liverpool in the league, that is just unfortunate, but once he fit, he has to perform to his maximum best.
