Premier League chiefs have questioned the relationship between Tottenham and Portsmouth.

The Guardian says no one has made a formal complaint and no one has any proof of collusion. But the dizzying amount of transfer activity between the clubs this summer, which has seen Peter Crouch and Niko Kranjcar swap sides with Kevin-Prince Boateng and Jamie O'Hara, will give them more to talk about.

Any supposed mutually beneficial links are unlikely to have been affected by Sulaiman al-Fahim's recent takeover: the former owner, Alexandre Gaydamak, and the chief executive, Peter Storrie, remain on the Fratton Park board.
