Gael Monfils is one of those players you either love or hate, but even if you hate the Frenchman you can't help but love his hustle when he's really trying his hardest.
In the ABN Amro World Tennis Tournament in the Netherlands, Monfils was up against Juan Martin del Potro and while del Potro won the match 6-3, 6-4 it was Monfils who pulled off the shot of the match.
The camere angle is a little strange, but just look at the speed of Monfils to get this ball and hit a winner out of it. Seriously, just look at the contortion of his body when he gets to that ball. Monfils definitely will see your tweener and raise you a level of difficulty.
