David Ferrer, who played seven tournaments in seven weeks prior to the ATP World Tour Finals, said the long journey took a toll on him in London. The Spaniard went 0-3 in his round-robin group.

“I know is a lot of tournaments,” he said. “But after last year I want to play in Stockholm because I didn't play too many matches. Well, I did final in Stockholm, final Valencia, final Paris, and three matches here. Is too much. But now I know it's too much. Before, I never know it. I did three finals in three weeks, no?”
