Tottenham chairman Daniel Levy has called on the Premier League to carry out a review the transfer system.

Levy was unhappy over Liverpool's and Manchester United respective pursuit of Robbie Keane and Dimitar Berbatov.

Spurs reported both clubs to the Premier League for unsettling the pair with the strike duo handing in transfer requests to leave White Hart Lane.

The pair have now moved on after Spurs dropped their complaints over the approaches and Levy says how clubs conduct their transfer business must be resolved.

"There are no guarantees in football and this summer we found ourselves having to deal with the unexpected challenge of both our leading goalscorers making it clear they wished to leave the club," Levy told the club's official website.

Review

"I have already stated my opinion on the manner in which our players were approached and the nature of the negotiations surrounding Robbie Keane and Dimitar Berbatov. Yesterday's (Monday) events were further evidence of the need for the Premier League to review the system.

"I have also previously said that we had no need to sell players on long contracts - this no longer remains practical.

"The decisions we took to allow the transfers of Berbatov and Keane were made after close discussions with the coaching staff. Juande was clear, and I believe correct, in not wishing to embrace any player within the dressing room that had no desire to play for the badge of this club and for his team-mates. Under these circumstances we had no option but to sell these players."

Levy is confident Tottenham still have a strong squad, with big things expected of Russian striker Roman Pavlyuchenko, who joined from Spartak Moscow, and Fraizer Campbell - the United player who moved in the opposite direction to Berbatov.

Confident

"I should hope that fans look at our squad today and acknowledge the undoubted talent and quality of our new signings," Levy told his club's official website. "But I cannot deny that I share with them a disappointment that we couldn't add further to replace attacking options.

"It has also been the case again that because we have been a buyer in the transfer marketplace we have been subjected to much speculation and our name has been connected to deals and situations that we had nothing to do with; attempts by selling clubs to push the value of players up has also seen us wrongly accused of not wishing to pay certain sums, again unfounded."
