A few days ago in Basel, Stan Wawrinka spoke about the effects caused by the two Grand Slam titles, Australian Open 2014 and Roland Garros 2015, that changed his life but not the Fab Four composition.
'Fab Fours are Federer, Nadal, Djokovic and Murray, what they are doing now, they have been doing it for 10 years! It's excellent. We compare me with Murray, I won 2 Grand Slams, but he has 35 ATP Titles! No really, I'm far away from them' admits the Swiss.
His life has changed also on Tour. 'Someone has become a little bit jealous of me and of the fact that I won two important titles. Others are happy for me and respect what I did. There was a big change after the Australia and again another even if less significantly at Roland Garros. Now there are things that I can't do. I've to protect my image, have to take care more. But it would not be fair to say that I regret the past. Let's say that I worked very hard to do all the things I do, and I did better than what I hoped! But it's clear, it's not easy to be constantly under the spotlight. You've to be used to that'.
His 2015 season 'was exceptional, I started hoping to win a tournament and to qualify to the Masters. I won 4 titles, Roland Garros...
it was a dream season. It's true, I would have liked to face Novak Djokovic onto the semifinals at Wimbledon, I would have been curious to see what he would have done one month after the French Open Final... I watched some highlights of that match, but not the entire match. I was so nervous before the match, as always happens in these circumstances. But I was confident since I did something great through that two weeks, I was Zen. Against Novak I played my best tennis'.
2020 OLYMPICS? WHY NOT! - Next March Stan will turn 31, 'I'm becoming old, eh? I want to keep going for several years, right now I don't see why I should retire'. He would like to play Olympics in Tokyo: 'I had positive vibes in that week this year (he won the tournament). It was special and I think that would be beatiful to continue at least till that event to play Olympics for the fourth time. Also, to live other emotions'.
Now he has to think about preparing well for Olympic Games in Rio 2016 next year. It could change his schedule, especially for the Davis Cup. From four to six March, Switzerland will face Italy away from home: 'It's clear that it's complicated to play first round in Italy and on clay. This event overloads the schedule. And now that we won, let's say that it's not so exceptional'.
