West Ham United assistant manager Zeljko Petrovic believes Tottenham ace Rafael van der Vaart could become a Premier League superstar.
Petrovic played in Holland when Van der Vaart was making his name at Ajax, and they had a brief spell working together at Hamburg when Petrovic was assistant to Martin Jol in the 2008-09 season.
Petrovic said: "I'm sure Van der Vaart will catch fire in the Premier League. Just like Dennis Bergkamp, he is brilliant at playing between midfield and attack."
