I have to confess, I've just watched a few highlight reels of him when he was at Mainz and he does have a style that has similarities to Lineker's, with the obvious difference being that he hasn't been anywhere near as prolific.
It's strange because most of his goals for you (with the exception of that overhead kick against I think it was Newcastle) have been exceptionally lucky finishes, either benefiting from a lucky bounce, deflection or rebound. Watching him playing for you, I assumed that finishing wasn't remotely his strongest point as there is so little evidence to say otherwise. But the goals he scored in Germany were often very, very nice finishes.
