Spurs chairman Daniel Levy yesterday made an official complaint and asked the Premier League to look into United’s behaviour over Berbatov and Liverpool openly targeting Robbie Keane.

A source at the club claimed the Berbatov affair was the straw that broke camel’s back.

Spurs have told the Premier League they believe it’s been almost a season-long pursuit of the player and want a special committee formed to keep track of any tapping.
