Rafael Nadal says he is refreshed and ready to face the world\'s best again after taking a break from competition over the past month.In the wake of his defeat in the US Open final, the Spaniard claimed two thumping Davis Cup wins but was not able to maintain that form when the ATP Tour headed to Asia.He reached the final in Tokyo but was crushed 6-0 by Andy Murray in the deciding set, winning only four points, before being shocked by Florian Mayer in the third round of the Shanghai Masters.After that loss he opted to take some time off to regroup and will head into the ATP World Tour Finals in London with a positive mindset.\"I played very good matches in the Davis Cup semi-final and after that I felt I was in good form,\" the world number two said.\"I went to Tokyo and I played a good tournament. In the last set against Andy I played bad but he played fantastic. It was hard.\"The loss in Shanghai was difficult for me because I felt I was in a positive moment and I had an opportunity to play a good tournament and I had a bad loss against Mayer.
