After watching him in most games during this season, he doesn't seem to "stick his head in where it hurts" when the opportunities are needed. He often/occasionally leads with his feet to try and clear the ball, when the balls in a heading position. This makes him look weird when jumping in the air to volley the ball away, and not opting to head it. As a defender myself (not professional at all ) using your height and heading it has always been the best way to clear the danger, and when Fonte does decide to kick it, the ball normally ricochets off one of our players and then to the opposition in the box. You may not have noticed this yet, but if you take a look at Fonte in action you should notice it! It's pretty obvious!
I have noticed on several occasions he will use his feet at times rather than his head. He often will also allow the ball to bounce in front of him rather than head it well clear when being pressed by the opposition. More often than not getting himself and the team into difficult situations because of this. This is his one weakness in my view.
Yeah, go and look it up on Google translate. Jos is a little... squareheaded. When he was newly arrived from Celtic, the Lads [Lallana, De Ridder, Chaplow and then Hooiveld himself] played a little joke on Twitter, taking photos of themselves wearing boxes on their heads with eyes in the corners. One or two of them looked quite funny.
He's also a hugger, likes to get a bit too close to the opposition and give away some unnecessary free kicks.
