The Liverpool defender has become known for his strength.

Liverpool centre-back Mamadou Sakho made a name for himself when he once broke the weights machine with his legs in training.
But, now, it looks as though the Frenchman has strength coursing through his whole body - not just with what he uses to run and kick a ball.
Indeed, Sakho took to Twitter on Friday morning with a video of himself in training but not just any training. Here, the defender was in the ring and doing boxing exercises.
As if people weren't fearful enough of the Liverpool man already!
The 25-year-old had the look of a proper heavyweight boxer: quick, strong and living up to his reputation as a tough centre-back for both his club and country.
On the pitch, of course, Sakho will have to show a lot more than just raw physical ability. His strength has been a huge bonus to Liverpool in the past but he has often looked clumsy - especially in possession.
Perhaps the Reds defender's boxing training can help improve his footwork and give him a more rounded approach. A big Sakho season is needed at Liverpool.
