Jermaine Jenas admits Tottenham have concerns facing former teammate Jermain Defoe with Portsmouth today.

He said: "Jermain wanted to go in January and sought other options and I've seen from training with him for England just how sharp and hungry he is.

"We must be careful for Portsmouth could be like a wounded animal waiting to pounce. But we are unbeaten in three league and cup games and have tremendous unity within the squad."
