When we announced his appearance, thousands of extra tickets were sold,' the 1996 Wimbledon winner said. He also added that the presence of top-ranked players like Federer and Rafael Nadal helped in the stands being sold-out.
Krajicek also spoke about countryman Robin Haase's potential: 'I will not count out that a Dutch player will ever win a Grand Slam. You have to be lucky, but why can't Robin Haase win such a big tournament? He improved a lot last year.' ALSO READ: Roger Federer trains in Rotterdam, to play Bemelmans in first round .
