Nishikori beats Ferrer: Five great shots

Watch five of the best shots as Kei Nishikori fights back to beat David Ferrer 4-6 6-4 6-1 at the ATP World Tour Finals.

Ferrer, who was not in the original draw, replaced Canadian Milos Raonic, who withdrew through injury earlier on Thursday.

Nishikori will progress to the next round unless Andy Murray beats already qualified Roger Federer in straight sets, a result which would see the Briton go through in Nishikori's place.
