Murray extended his winning run to 24 matches, the best run in his career.

The victory also ends Djokovic's four-year run of success at the tournament.

A capacity crowd of 17,000 packed into the O2 Arena to witness the match, and it was Murray who rose to the occasion.

"Andy is definitely number one in the world," said Djokovic. "He deserved to win. He is the best player."
