Hmmm, a bit difficult to tell. Definitely not the ball-playing type, I mean he's very solid in posession and I've never seen him make any real mistake, but he's not capable to play any long-balls Bonucci-style. In terms of defending he's more of a Barzagli/Rugani type than Chiellini, though there are instances where he goes full King Kong on an attacker out of nowhere
That's all from watching Austria matches where Hinteregger plays more aggressively usually and Dragovic in a more reserved role, could be that he plays diffeently for Kiev.
He's not starter quality really for us now, but he's solid and hardly ever brain farts, plus could develop into at least borderline starting quality over the years. For the 15-20 million he's rumoured it's a good buy in today's market, we'd be settled for years when it comes to CB rotation.
