Video: Andy Murray gives himself a haircut during World Tour Finals match against Nadal

World number two Andy Murray gave himself a quick haircut during a change of ends in this afternoon's ATP World Tour Finals contest against Rafael Nadal.

During the first sit-down break of the match at the O2 Arena, Murray removed a pair of scissors from his bag and trimmed his fringe after seemingly determining that it was too long and off-putting.
