"They are very different from the last time we played against them: Gomez, the goalkeeper, is now at Spurs; Phillip Cocu has retired; and a lot of other players have also gone to other clubs," said the Dutch international.
"They are a totally different side but they are still the best in Holland. They have won the league six times in a row, I think, so they're a very good team and we have to be ready."
