Eurosport - Switzerland's Roger Federer poses with his trophy after defeating France's Jo-Wilfried Tsonga in the final of the Paris Masters tennis tournament
"It's just too much, I was trying to make up my mind and I had some little niggling stuff I didn't want to take a chance on," he told reporters after losing to Juan Martin del Potro in the Basel Open final.
"I feel very disappointed. I had one of the best weeks of my life there last year, but this is just a last-minute decision."
Rafa Nadal has also pulled out of the tournament as he continues to recover from a knee injury.
