Manchester United chief executive David Gill has claimed the Old Trafford outfit are 'not embarrassed' by revelations they paid £2.1million to agents last year.The sum has been detailed in United's latest financial results and represents an increase on the figure of £1.8million which was sent in the 12 months to June 2006. Indeed, not only do the Red Devils defend the expenditure, they have called on their Premier League rivals to follow their lead in disclosing agents' fees. Although the Football League have adopted a policy of transparency with regard to dealings with agents, so far this has not been embraced by the top flight. United first started publishing agents fees in response to the infamous `99 questions' posed by then major shareholders John Magnier and JP McManus. As a privately owned operation, under the control of Malcolm Glazer, United now have no need to publicise any figures at all. Yet Gill, an influential member of the Premier League board and FA international committee, feels it would be in the best interests of the whole game if the Premier League started to become more open. 'We are not embarrassed by the figure and we do not see why other clubs should be either,' he said. 'Part of the way of doing business and attracting players, not just in this country, is to use agents. 'I am not worried about the figures. It is the market we operate in. 'I think publication of these figures is a good thing - 19 other clubs do not.'
