Frenchman Comolli played a key role in persuading Ramos to leave Sevilla and take over at Spurs.

Ramos has enjoyed an unbeaten start to his reign since replacing Martin Jol last month, but Levy made it clear he saw the Spaniard as Comolli's man.

Levy said: "Damien recommended Juande Ramos, so clearly he would have to take responsibility if it didn't work.

"I have every confidence it will work."

Comolli's role has come under scrutiny but Levy added: "Virtually every club in Spain has a sporting director.

"We want a coach who specialises in getting the best out of players, which means making the team selections and making all the tactical decisions.

"What the sporting director does is take a lot of the pressure off the manager. They can go on scouting missions and be in charge of scouts.

"They also have to be in charge of the medical department and the academy, and it is impossible for one person to do everything to the best of their ability.

"Having said that, there are always exceptions, such as Arsene Wenger at Arsenal and Sir Alex Ferguson at Manchester United.

"But the best chance of success is if you have someone looking after things that are outside the first team, and one who looks after the first team.

"Then, they can come together over the question of transfers."

Levy also refused to confirm that striker Dimitar Berbatov's long-term future lay at White Hart Lane.

The Bulgaria striker has been strongly linked with a move away from White Hart Lane and has scored just three times so far this season.

Levy added: "No person is bigger than the club. I very much hope Dimitar will be here at the start of next season but I hope that most of the first-team players will still be here.

"It's always difficult talking about individual players coming up to a transfer window, but I don't expect any of our players to leave in January.

"I very much hope they will be here in the summer. But summer is a long way off and a lot can happen between now and then."

Levy also passionately defended his decision to dismiss Jol last month, even hinting that the club could have been relegated if the Dutchman had remained in charge.

Speaking after taking testing questions from shareholders at today's Extraordinary General Meeting, Levy claimed he and the board had no alternative but to show Jol the door after he "lost the confidence" of his squad.

He added: "We wanted Martin to succeed. The outside publicity was unfortunate but, in the end, it comes down to results.

"You can't have a situation where everybody is talking about finishing in the top four and then being in the bottom three.

"You cannot afford to take the risk that you may end up in a very, very bad situation. No club is too big to be relegated.

"We just weren't winning at all and you could look at the players and there was a point when I think Martin had lost the confidence of the players. That happens in football."
