AS Roma goalkeeper Maarten Stekelenburg is delighted with his personal form.

The Dutchman is determined to shine at next year's World Cup.

"I'm now happy," he told the Corriere dello Sport. "I'm no longer thinking about Fulham and I no longer want to leave Roma.

"I want to stay and I want to become the best goalkeeper of the World Cup that will be played in Brazil in 2014."
