I have similar views on Hojlund as when we signed him.
Namely, that he looks a good, raw prospect and definitely has the ability to do a decent enough job now and the ability to develop into an even better one over time.
However, the problem was always that he clearly wasn't yet the finished enough product to be our first choice lead the line striker straight away. And so we needed a much better, experienced striker sharing that role rather than the likely to be always injured Martial.
If we'd signed him under different (the right) circumstances - more realistic fee, initially understudy to a senior striker, better service for our #9, etc - then he'd have had a far easier integration. As it is, he's really being thrown into the deep end - but hopefully those PL goals will ease the pressure that was ever building and he'll be able to build some confidence and go on a decent run.
Long term, I've seen enough to suggest there's definitely a decent prospect there. But no way, short term, should we have ended up with him carrying the burden of being our main / only #9 this season.
