If memory serves me correctly they all got fired by Levy after not winning anything.
Poch was truly incredible with us, but I thought it was universally recognised by all Spurs fans that he ultimately failed (and when he went he needed to go!) because Levy did not invest any money in the 1st team for 2-3 years, and the squad aged, went very stale, and lost all momentum.
Redknapp could have had a shot at the league in January but Levy bought him Saha and Nelson when we needed reinforcements, and then he shot himself in the foot by chasing the England job and getting accused of taking bungs.
I won't comment on Jol as we were a much smaller club them in terms of revenue and were unable to compete with the 'Sky 4' at the time, and could not have been expected to win anything.
