So i guess it is ben arfa fault that de jong the thug decided to scissor tackle with more force than needed and to bend his right knee to make contact with ben arfa,you can see that de jong could have stayed up and just bugged ben arfa if he wanted to as tevez was right there next to him so he had no other way to turn to but no,the maniac that he is just can't think properly and know that being a destroyer doesn't mean lunging at every opportunity.
The problem is not that he broke ben arfa leg but more the way he tackled hatem with such force that it caused the leg break,call it luck and ben arfa being unlucky but it is too many players who have been on the receiving of stupid and needless nigel de jong excessive force to say the man isn't too overly aggressive,you just have to look at some of the youtube clips of him to know he doesn't care if he takes out someone as long as he clears everything and that to me is wrong.
Tiote was also a destroyer yesterday and you didn't see him make this sort of challenges especially so early in the game which is what really makes this injury to ben arfa the more obvious for me that de jong wanted to send a message to hatem that if you go on them mazy runs of yours this is what is going to happen so in some way scare him or make him play a different kind of game.
Nigel is a good defensive mid who just needs to learn how to decrease the force that he uses to be less reckless and cost other players well being.
