I love a player that prides himself on contact aspects of the game - hassling, tackling, niggling and blocking. Not afraid to back himself and go in hard on a challenge. He's got grinta and you can never have too much grinta!
It's almost non-existent when Mandzukic is off his game and Chiellini is out. Matuidi works hard but somehow that's different to "grinta". Lichtsteiner and Vidal had it. Need more players with a bit of c*nt in them!
