Djokovic beats Del Potro to reach 02 final

Novak Djokovic fought back from a set down to defeat Jaun Martin Del Potro and reach the final of the Barclays ATP World Tour Finals in London.

The world No 1 had looked in trouble when he went a break down in the second set but Del Potro won only three of the last 14 games as Djokovic triumphed 4-6 6-3 6-2.

It is the first time the 2008 champion has reached the final since the tournament moved to 02 Arena three years ago and he will meet either Roger Federer or Andy Murray on Monday evening.
