Novak Djokovic proved his powers of recovery once again by fighting back to beat Juan Martin del Potro in the semi-finals of the ATP World Tour Finals.

The world number one came back from a set and break down to win 4-6 6-3 6-2 at London's O2 Arena.

With the year-end top ranking assured, he now has the chance to cap 2012 with his second season-ending title, reports the BBC.

Roger Federer takes on Andy Murray in the second semi-final at 19:45 GMT, with the final being played on Monday.

Djokovic had come through the round-robin stage with three wins and was keen to stress that his desire to take the title outdid any end-of-season fatigue.

However, the sight of Del Potro repeatedly winding up arguably the biggest forehand in the game would have been enough to excuse any opponent pining for the off-season.

Del Potro blasted his way to safety with his two trademark shots - a big serve and a thunderous forehand - when facing early break points, and Djokovic was soon being forced out of his comfort zone in the baseline exchanges.

A woeful attempt at a smash in game seven suggested the pummelling was having an effect and for the next six games it was all Del Potro - a running forehand winner getting him two break points at 4-4 and another heavy blow from that side converting the second.

The first set was wrapped up after 47 minutes and things looked bleak for Djokovic at the start of the second set as the assault continued from across the net.
