Barcelona are rivaling Real Madrid for Ajax striker Klaas-Jan Huntelaar.

The Dutchman's Italian agent, Vincenzo Morabito, said: "Real Madrid has taken a step forward in considering him the successor to Ruud van Nistelrooy. But we must also take into account another club, which must carry out a genuine revolution, with many changes and plans to build their team around Lionel Messi."
