PSV Eindhoven coach Ruud van Nistelrooy regrets leaving Real Madrid.

The striker joined Real Madrid in the summer of 2006 from Manchester United, becoming one of the star signings brought in by Ramón Calderón.

In his first season, the Dutchman became the top scorer, contributing to Real Madrid's successful campaign and their capture of the league title. Overall, the team won two league titles and two European Super Cups during his time at the club.

“I was with [Manuel] Pellegrini at the time [the manager] and they signed [Karim] Benzema, Ronaldo, Kaka, so there was no place for me. I understood, I accepted, I was 33," he told the Overlap.

“I wanted to give it a go to go to the World Cup in 2010, so I decided to go to Hamburg. I made that decision too quickly. If I look back, I shouldn't have left Madrid, it was the biggest mistake of my career.

"Also, it wasn't the right time for my family to leave either."
