I've got, and have always had, a fair few doubts about Rom. Doubts I wilfully pushed aside in that weird bout of self-motivated positivity that washes over you after every new signing. But I still feel it's too early to write him off, or go full metal jacket on him. He is young, and the top scorer in the second highest scoring team in the league. So not exactly DOA...However, I do want to take issue with one particular recurrent line of defence.
The idea that he just needs better service, or a more favourable system is all well and good, but a Manchester United striker shouldn’t really need either of those things. Sure, with a proper RW he might have 4 or 5 more goals, but if he was a genuine world class forward he'd have 9 or 10. When we had Giggs & Becks on the wings people used to say any striker could score 20 a season at Man Utd. Yet at no point during that time did we actually have just a “decent” striker. Because why would we? Who builds a world class midfield just to set up goals for a decent striker? Strikers cost the biggest bucks. A Manchester United striker should thrive when given chances, but also be able to create them out of nothing. Otherwise what’s the £££ for? When we could apparently just stick a pole on a Rumba and “give it better service”?
Our most recent title win was almost entirely down to having a striker who was threatening from anywhere. Who could win a game even when our midfield wasn’t firing (which was often) That's why we bought him! That's why clubs like Man Utd buy strikers. That's why they're expensive. If he needs it put on a plate he’s not up to snuff I’m afraid.
The whole of your middle paragraph is why I wouldn't have gone near him at any point in time, personally. The technical level, that brilliance and innovation, he lacks it. There's no guile to him and no finesse. There's also a lack of deftness. This is my own subjective issue, admittedly, because I like my strikers to be brilliant and nothing less than that will do - RVP, Yorke, Cantona, Rooney, RVN, Saha and so on at their best epitomised the magic I've come to expect from a United striker.
That feeling something magical may happen is devoid when it comes to Lukaku. That's not his fault, and it's not an issue, per se, but the raw, blunt force style of play has limitations unless your name is Peyroteo. Even then, in terms of iron-handedness, Lukaku is not a hard-man or any kind of Drogba or Duncan Ferguson or Joe Jordan etc. etc. so he's a bit of a nomad when it comes to definition as a player at the level he's being asked to play at - you also can't put all your hope in him like you could with a number of forwards listed for us in the previous paragraph because you've half a mind he's not up to it when push comes to shove.
Still, these may be growing pains and, perhaps, he finds his own way and unique style whilst here. As he is not a player with magic in his feet, you have to turn to the next best thing and hope that supply to him can be plentiful enough that he gets his chances to convert in the way that he does. As you say, that's not what we're used to here (strikers who can't make their own chances) but that is by-the-by, as Lukaku is our #9 and we've got to do what we can to facillitate
his game. The benefit to that, however, is that with or without Lukaku in the team, an elite supply line will be fantastic for whoever gets the gig and can help us to grow.
I'm not entirely sure how long Lukaku will get to make his probation a permanent tenancy as our uncontested #9 - the notion he'll have years to do so, I'm not sure of because if Mourinho catches wind of a true elite striker being available, he
will snap him up - but whilst he has his chance, you have to hope things can work for him, and by proxy, us, as it would enable strengthening and financial outlay elsewhere without growing concerns our #9 will need to be improved upon sooner rather than later.
Even if his style is not the preferred way for an elite striker, the measure of him is going to be what he can do vis-a-vis what he cannot when the team is moulded to suit his game. I feel that is the time Jose will be looking at him with judgmental rather than sympathetic and hopeful eyes and at that point, he'll either find himself out of the team or out of the club if he cannot handle either the competition for his place or the notion of being a sub rather than a starter.
