Polvara has a strength to him that's lacking in our other midfielders. When we took him to Pittodrie, he was featherweight and felt like he was just a signing to keep Christian Ramirez company. The following off-season he clearly hit the gym, and came back much more of a physical threat. We saw that when he came on on Saturday too, didn't get pushed off the ball by Hearts' cavemen. I hipe he gets utilised more regularly by JT - between him, Clarkson, Palaversa, there's good options in the middle
