Nikolay Davydenko is ready to put his defeat at last year’s ATP World Tour Finals behind him by beating Juan Martin del Potro at the O2 Arena on Sunday.

The Russian (6/5 to beat Del Potro in the tennis betting) came through an epic three set semi-final with world number one Roger Federer to book his place in the final, holding his nerve in the last set to win 6-2 4-6 7-5.

The world number six hadn’t beaten Federer in 12 previous attempts but finally got the win he has craved to send the tournament favourite crashing out and reach the final for the second year running having lost to Novak Djokovic in Shangai 12 months ago.

Davydenko will now face US Open champion Del Potro (8/13 to win the final in the match result market) after the Argentine came through his own nail-biting semi-final with Robin Soderling 6-7 (1/7) 6-3 7-6 (7/3).

While Davydenko is hopeful of overcoming Del Potro, whose win over Federer in the group stages eliminated home favourite Andy Murray, he admitted he was drained by his semi-final with Federer and the long week of tennis that preceded it.

“I think all my family, everybody who’s supported me, waited for this moment when I can beat Federer, because I beat everyone in top 10 except Federer. It’s a really good feeling,” said Davydenko.

“I was tired, really tired,” he continued. “I want to recover 100%. I hope tomorrow I’ll be fit for the final.”
