Tottenham have an "amazing" talent on their hands in Adel Taarabt, says manager Martin Jol.
Jol believes Taarabt can have a huge impact and said: "On the ball I don't think there's another talent like him in England.
"I want to play him in the hole, but for an 18-year-old lad he is not covering a lot of ground so that is why we will work on him every day.
"He must be a bit sharper and if he does that he can make our stadium like Sunderland's Stadium of Light. Adel is amazing. Even when he loses the ball three times, he still tries for a fourth time.
"But if he loses a lot of balls and you're 1-0 down, then the crowd will be less pleased with him. He's got to learn to combine all his qualities and be a team player as well."
Such has been Taarabt's impact at the club, even first-team regulars feel they have been put in the shade in training.
Midfielder Jermaine Jenas said: "He's a great lad and has ability in abundance. He still has a bit to learn but he is a breath of fresh air. Sometimes you stand back in training in awe at what he can do. I'm sure with the manager and coaches we have here, there is no better place for him to learn his trade."
