He isn't a 16 year old from the swiss 4th division, he's been playing in the Bundesliga for years and has tons of caps with Romania. He was rated when he first broke through but fell off the radar.
You forgot to mention he made 223 league appearances in those 12 years (with a lot of those appearances off the bench).
Putting him on a par with Bendtner as a 1 in 5 striker, except Marica also knows how to control a football. As I said, nothing special but he could tide us over until the January window.
