€15m doesn't get you much now, and he's a young striker in-form.
Thought he had something special about him as a young striker, obviously massive but had lots of nice touches and scored quite a few goals. Italian coaches tend to use him more as an old-fashioned target man but he had a breakout with Perugia and partnering Han and others, German football could suit him.
Needs a buyback clause for sure, we can't throw away potential big Italian talents.
