VIDEO: Serena Williams orders Espresso during match, drinks it and goes on to win

Serena Williams really likes coffee.

That's what we learned today as the world number one needed a lift after losing the first set against Italy's Flavia Pennetta 6-0 during a Hopman Cup match.

The American found her own request laughable as she asked the umpire if it was legal to order an Espresso.

The umpire was feeling generous and permitted the request and sent a ball girl to fetch the coffee.

The caffeine boost clearly worked as Williams went on to take the match 0-6,6-3, 6-0.

We have to start drinking more coffee.
