"JJ is 22 and has great ability. He is getting stronger each year.
"He is very fit and has great energy to get up and down the pitch. He can score goals and also play holding midfield," said King.
Tom Huddlestone believes that former Derby County teammate Grzegorz Rasiak ‘will take the step up in his stride and do well for Spurs.’
"He is big striker, good in the air and can hold the ball up well. I know it is said a lot but, for his size, his feet are very good. He's got a bit of pace and his finishing is probably his strongest point - which is obviously a bonus for a striker.
"Saying he is a complete striker might be a bit over the top but his passing is probably as good as his finishing," said Huddlestone.
