I don't think Lukaku is a donkey......you don't score as much as he has by being a bit shark......but I am worried he's just a more expensive version of Louis Saha.
Not so worried that I don't get a good nights sleep, mind you....or suffer from ED.....
Louis Saha and Lukaku are in no way comparable players.
You're right - aside from the pace (Saha more so), power (Lukaku more so), being good in the air, both being left footed, both coming to OT with plenty of Prem experience, they have nothing in common.
Lukaku's first touch not as good as Saha's mind you.....
Apples and oranges, despite the fact that they're both big, quick and black, which you seem to be basing your comparison off.
