Tottenham target Jan Vertonghen is furious with Ajax over the leaking of his contract details.

Vertonghen is entitled to 15% of the agreed £9.5million transfer deal under the terms of his deal with the Dutch champions.

"I'm shocked. The percentage is correct - it's unbelievable. I know that at Ajax a lot of things are leaking," he said.

"When you hear it about other football players, you don't feel it. It's different when it's about yourself."
