Liverpool defender Mamadou Sakho is happy to play on the edge.
Sakho admits he regards games as a "war".
"For me it is war and I'm not afraid of anyone. I do boxing in addition to my normal training and I am having my punchbag and boxing kit sent over from France.
"Before I joined Liverpool I fought at a Paris gym owned by the kickboxing champion Aurelien Duarte and I trained with his cornerman Alex - a crazy Serb. Alex said I have levels of fury he has not seen in some fighters."
