The Finals are Federer’s last chance to win a big tournament this season. He has won only one title in the past 14 months and has only three victories against top-10 opponents in 2013, including one against del Potro in Paris last week.
“I’m glad I got one back in Paris because I knew we could be again in the same group, we could be playing each other,” Federer said. “I think that win for me in Paris psychologically was very important. I could beat top-10 guys, I beat Richard, I beat Juan Martin last week. I truly believe my confidence is higher, and that’s what I need to beat the best, and Juan Martin is part of that group honestly.
