But the German raised striker, who is wanted back in his former home by Borussia Dortmund, it was a loan spell with Atromitos in 2011-12 that really saw him come good - and now he looks like becoming the finished article at Olympiakos after a magnificent turn of form.
But last night we reckon was probably the best goal of his young career yet.
The £25 million forward bagged a last minute winner in what is sometimes described as the most ferocious derby on the continent - dubbed the Derby of Eternal Enemies and the Mother of all Battles, Olympiakos v Panathinaikos.
He battled through on goal before slamming the ball beyond the Panathinaikos goalkeeper to claim their 76th win in this heated and historic derby.

Liverpool and Arsenal fans would love to see him do something similar against Everton and Tottenham respectively.
