"I'm desperate to be a footballer," he admitted to the Daily Mail.
"I am a footballer. I want to be a top footballer. There have been loads of setbacks at Tottenham, but then there are setbacks for players at every club.
"I'm only human and I made a decision to leave Palace which I thought was the best for me.
"Palace fans were frustrated, but I didn't want to frustrate them - I'm still a Palace fan and I went to every home game between the ages of five and 15.
"Sometimes I look back and think what might have been, but I was a young player. I was hungry and I wanted to develop."
