Tottenham, Not Ready For The Top 4

In any one game, even the best of teams can fall apart. It doesn't happen often, but it can happen. But that is not the case for Tottenham. Going into their last league game against Fulham they only had 2 clean sheets in their previous 22 league games. And the letting Fulham come back from 3-1 to tie it up at 3-3 made it 2 of 23. If they really want to be a big team they need to tighten up their defense. Is Martin Jol the man to do it? Or is it time Spurs cut the cord and found a better manager?
