The transfers centre around eight English league clubs and Premier League chief executive Richard Scudamore said that Lord Stevens' Quest team will be given a further two months to complete their work.

"This is something Premier League clubs wanted to do, and has been done with full support of the clubs who wanted a thorough, professional and credible process to deal effectively with any irregular transfer payments," Scudamore told a press conference.

"We have as a group unanimously agreed to extend the period of inquiry by two months in order to investigate transfers that are in need of further investigation."

Lord Stevens and his team looked into 362 transfers, covering the period from January 1, 2004 to January 31, 2006.

"I have briefed all of the chairmen and chief executives of Premier League clubs and this interim report remains a work in progress," Lord Stevens said.

"Quest, under my leadership, has managed to examine 362 transfers and reduced that down from that to 39.

"They are within the English game and require further investigation before I am prepared to sign them off. These involve eight league teams.

"The work conducted led me to make a number of observations regarding administration and monitoring of the transfer market. These were made to the chairman and chief executive of the Premier League.

"Once the enquiry is complete we will report these as recommendations for consideration by the league.

"I would like to express gratitude to the clubs and regulatory bodies and others involved in the game for their unanimous support."
