He will get a bit more time and probably at the very least two seasons to prove himself as the United no 9. It sucks that the team currently isn't where it should be but the likes of Cole, Yorke, Van Nistelrooy, Saha, Rooney, Tevez, Ibrahimovic, Berbatov, Cavani, van Persie even Martial could create something for themselves, could make a goal out of nothing, create some magic. I really don't want to hear this talk about service all the time, if he is so reliant on service and service alone (I'm not saying service isn't important, all strikers need service to a degree), he shouldn't be Manchester United's main striker and we should be looking to upgrade in that due time.
It seems like the club doesn't see him as that striker right now, but at the very least in the coming season we have to see the glimpses that he could be. I saw those glimpses with Hojlund in his first period, but even far too few. He was way less reliant on service under EtH in the first period, than under Amorim especially.
