He's doing well so far, but it's way too early to say if he's the real deal. Every year we see a handful of young 18-20 year old players who show a lot of promise but never develop into a top-tier player in the long run, and I can't say that it's obvious to me that he isn't one of those. He scored quite a few goals at Sturm Graz, but that's the Austrian league so I don't know how much that's worth. Now he has scored 8 goals in 25 appearances for Atalanta, which isn't exactly Haaland-level. He generally plays well when I watch him and he shows a lot of promise, but I'm guessing he would cost a lot and I have to say it would be a gamble. He's just as likely to be another Martial as the next big thing.
His goals for Denmark are such a small sample size that it doesn't say much. If we could get him for like £30-40m, I'd say it's worth a shot. If he costs twice that, I'd be hesitant because he's still rather unproven in the grand scheme of things. He has had a single season in a "real league," and while he has done fairly well there, he hasn't taken Italy by storm and put out incredible numbers. Eight goals in 25 appearances isn't exactly astonishing. In terms of what they'd done before coming to United (if he comes), I was more optimistic about Antony than I would be about Højlund. He has not yet made me feel like he's definitely the next big thing, but I'd be happy to give him the opportunity of the fee isn't ridiculous.
I'd rather have Osimhen. If we make Højlund our primary striker target this summer and get only him, I'd be worried. He might live up to the expectations, but I don't think it's highly likely that he will. I give it a 50/50 chance whether he'll be the main striker at a top club in a few years, or playing for Celta Vigo or something. It's nowhere near a sure thing that he'll grow into a top striker. Osimhen will cost a lot more, but he's a much safer bet as well. If we could get both, I'd be ecstatic. If we get just Osimhen, I'll be satisfied. If we get only Højlund, I'll be very nervous and I think the club would be gambling too big on a definite maybe. We need a dependable striker right now, and a prospect for the future would have to be a side-dish.
