Ferrer fell short of becoming the first player to successfully defend the Paris title while Djokovic took another step towards regaining the No 1 spot from Rafael Nadal heading to the World Tour Finals.
“I’m full of joy right now. This is one of the biggest weeks of the season, so I’m really happy and just want to continue like this,” said Djokovic.
