I can vouch for you guys on Lukaku...I picked him up at the start of the 2010-11 season for my Chelsea side and he's already got five goals for me, including one in the 88th minute to knock Man United out of the League Cup. You might also want to have a look at Mario Balotelli from Inter; though he's got the size to be a target man, he's more of a playmaker than anything. If you can train him well, he may even be able to be cast in the Complete Forward role like I do with Drogba. It'd be worth looking into.
