Chelsea advisor Piet de Visser says Manchester City star Robinho can become a great of the game - if he takes the next step.

"Robinho was a great talent," said De Visser. "I saw Romario, Ronaldo and Robinho at 16 years old and Ronaldo was a little bit more of a killer than Robinho, scoring more goals. Robinho is more of a second striker and a winger.

"To become like Ronaldo and Romario, he now needs to take another step. He has to step up to become a great player. He has scored a lot of goals as second striker but he is still a little bit brilliant one game and not so good the next.

"Guus (Hiddink) and I wanted him very much but the PSV directors would not come up with the money. We were very close to getting him but the price was nine million euros and the directors said it was too much for a young player.

"We thought he was worth it and it was very disappointing. Madrid eventually paid 24 million euros because by the time they bought him he had made his debut for the national team. So PSV lost a lot of money."
