As a Belgian who follows the PL regurarely I'm pretty excited Lukaku finally going on a loan to another club. I was already a bit interested when El Ghanassy signed for you guys(he came from my favourite club), but now I'm definitely going to follow WBA with Lukaku.
Lukaku is a great talent, but I can understand the scepticism of some people here however. I believe that if Lukaku gets enough playing time and confidence that he will be able to score 10 to 15 goals for WBA this season. His top speed is great, he's as strong as the hulk and might get even stronger considering his age, his passing is decent(and a great cross actually, but as an CF it's something you don't have to use very often) and he can score a good amount of goals if he gets confidence. And his mentality is good.
His downsides are his acceleration(although it's not bad, but Drogba's acceleration for example is way better), his inablity to create chances or weigh on a defence when it's a closed game(but he's still young, that can improve with experience), and probably his biggest setback: his ball control. This last thing is really something he should work on, it's the only thing that really worries me in order for him to become a world class striker. The problem is that a good ball control is usually something that you have the knack for or you don't, it's hard to train that. He should also try to improve his heading, it's not bad but considering his body and height he should try to be awesome in it.
The press also said that he's the new Drogba, but I never really agreed with that though. He's a different kind of targetman, if you could compare him to anyone then I would say that he looks more like Adebayor in his style of play. Don't expect him to crack open every defence in the PL this season, but I'm pretty certain that if he gets enough confidence that he will be a solid striker for WBA this season.
