Nadal: I was lucky to win

An ailing Rafael Nadal admitted he was fortunate to begin his Barclays ATP World Tour Finals campaign with a victory after coming through a near three-hour tussle against Mardy Fish in London on Sunday night.

There were question marks over the world number two’s form going into the match - his first since losing to Florian Mayer in Shanghai a month ago – and those remain following a 6-2 3-6 7-6 (7/3) win at the O2.
