The former Netherlands international believes that the two attackers have a long way to go until they reach the level of Lionel Messi and Cristiano Ronaldo.

"Bayern are a good team. They do not have many stars but the team is well put together," he told Bild.
"Lionel Messi and Cristiano Ronaldo are stars. They are of a different calibre than Arjen Robben and Franck Ribery."
Gullit is of the opinion that Robben's persistent injuries has hampered his career to a great extent.
"He is the best player the Netherlands have. But whenever you need him, something happens. His body is springing nasty surprises. He is injured far too often."
