Stanislas Wawrinka is more than capable of adding to his Grand Slam tally, according to 14-time major champion Rafael Nadal.
Swiss star Wawrinka secured the third Grand Slam success of his career by beating world number one Novak Djokovic in the US Open final last week.
Now just a Wimbledon title stands between the 31-year-old and a career Grand Slam having already claimed titles at the Australian, French and now US Opens.
Spaniard Nadal, who knows a thing or two about Grand Slam success, believes Wawrinka won't just stop at three major titles and has predicted more success.for the world No.3.
He told reporters: "Stan is a player that over the last couple of years has been playing great tennis. When he is playing well he is able to play very well against all opponents.”
