Former Manchester United goalkeeper Edwin van der Sar has admitted that he is not sure the Netherlands squad is strong enough to make an impact at this summer's World Cup in Brazil.

Van der Sar, who won 130 caps for the national side, said that there are only three or four world-class players in the current squad, which may not take them far in the tournament.

"We are in a little bit more of a difficult time now, we don't have the 10 or 11 world-class players in our team - we have maybe three or four and they are getting older," Van der Sar told FIFA.com.

"So it's about time that the young Dutch generation pick up the laurels from the older ones and hopefully can achieve, first with their clubs and then the national team, a little more success than over the last three or four years. No, three years, as four years ago we were in the final."

Van der Sar also played for Fulham in the Premier League during his career.
