Looking back at that final in which he struck 59 winners, almost twice as many as Djokovic, the Swiss player still relishes the win.
"For sure winning Roland Garros was my biggest win. Novak is an unbelievable player, he has played so strong during the whole year and deserves to be number 1. Beating him in the final meant a lot to me, it made me very proud. I played amazing tennis on that day and managed to find a solution against him," Wawrinka, who will open his 2016 season at Chennai Open next week, said.
The Swiss world number four is a two-time defending champion at Chennai Open and he was eyeing a hat-trick of titles.
"I've always enjoyed coming to Chennai. The tournament is a nice way to start the season, the fans are great and I like the atmosphere in the stadium. Of course I would love to defend my title, but I will have to go match by match," he said.

"I'm somebody who really likes to work hard. I like to get up early in the morning and enjoy practising a lot. That helps me a lot, because a tennis career is very much about working hard and enjoying what you do.
