The 20-year-old has been one of the discoveries of the season, scoring 14 goals, but has now set his sights on a move.

The American is under contract in Friesland until the summer of 2009, but Heerenveen may be forced to sell the wantaway star sooner.

He told the Ajax Life magazine: "I strive to reach the highest level. It's time to make the next step.

"I don't think the Dutch way of playing football suits me. I see myself as a box-to-box midfielder - I attack and score goals, but I also defend and I win many balls. In Holland it's often one but not the other."
