Roberts told Express Sport: "I liked him when he joined [Tottenham], I thought he was brilliant when he played for us, [Tottenham]. I remember him scoring two goals against Chelsea, two brilliant goals when we won 3-1.
“I have always liked him, I don’t know what went wrong. I tried to recommend him to Rangers a few years ago and said: ‘If you get hold of him and you help him, there is a player there’. There is a player there but he needs someone to put an arm around him to really get him back to what he was as a kid. He is barely at his peak yet, it’s frightening.”
