Clint Dempsey says he felt he needed to test himself by moving to Tottenham.

Dempsey left Fulham for Spurs last week.

Dempsey said: "For me, it's always been about being able to look myself in the mirror and say, 'You tried your best. You challenged yourself. And you'll be able to die a happy man in the sense of your career, knowing that you were able to see if you could do it or not'."
