Stan Wawrinka has won more Grand Slams than Roger Federer and Rafael Nadal combined over the past two seasons but the Swiss world number four insists that adding to his Major tally is a goal that is “too far away”. Wawrinka, who handed Novak Djokovic his only Grand Slam defeat in 2015 by stunning the world number one in the French Open final, will kick off his season in Abu Dhabi at the six-player exhibition Mubadala World Tennis Championship on Friday, but said winning a third career Major was not on his list of goals for 2016. Yes I know I won two Grand Slams in two years but it’s still something incredible for me, something not normal, so it’s tough for me to put a goal to win a Grand Slam again,” Wawrinka, 30, told reporters in Abu Dhabi on Thursday.
