We have all been aware for the last 20 years that the defense at Spurs is pants yet nothing gets done about it. We need world class players in the back 4. If it means we have to spend then lets spend and in the right departments.
Kaboul has potential and may be in a few years he will develop into a top class defender, but we need senior players with class and do not make simple mistakes now.
But sadly if i were a betting man I would have to say that that is not going to happen this season.
