Well he just played his first half season in the prime league, and considering the quality of our championship I wouldn't say he is quite fit to start right away for Feyenord. He really needs a hard work so that he would develop, but he really has the potential to do so. I'll say he is the most promising right back Bulgaria had in years. He's secure in defense, but still his rushes forward are not that good despite his relevantly good technique. He could develop a strong phisique anytime soon, though he'd never be really fast. And as far as I can judge his positioning seems to be his best quality yet, but I don't know how this could develop in ur league as here it's quite predictable to know what our wingers would do.
