First out the door would be Zokora, he's so unbelievably rubbish. Chimbonda, Robinson and Kaboul would follow fairly quickly.
Zokora is one of those players whose contribution is hard to see on TV. When Spurs push forward, he's the one filling in the gaps at the back. He's very quick and works hard for 90 minutes. He's also filled in well at CB. All he needs to do is cut out the reckless challenges and he'll be a very decent DM.
I feel sorry for Kaboul. He was obviously bought as a player for the future but he got dumped straight into the first team due to injuries. I'd give him at least a couple of years to see if he comes good.
Chimbonda and Robinson both need to go though. Chimbonda's attitude stinks and Robinson isn't good enough.
I don't think Spurs need wholesale changes. What Spurs need is the signing of two or three really top class players. Spurs were only a dodgy lasagne away from a Champions League spot when the likes of Lee Young Pyo, Paul Stalteri, Andy Reid and Mido were first team regulars.
Oh well, our season is over now. We can give us fringe players a run out for the rest of the season.
