"I think most clubs have to make it transparent,” Sir Alex told reporters.

The Scot has heavily criticised the money paid to third parties, blaming the existence of the transfer window for the ever-increasing demands, and hopes for an eventual removal

"I think most clubs have to make it transparent,” Sir Alex told reporters.

“Individually? I don't know how we could apply that. I don't see it doing any harm. It might highlight to the public how ridiculous it can be for some agents to make the money they do. But I don't think that will ever change.”

The Premier League recently released the spending of all 20 current top-flight clubs between October 2011 and September 2012, with United placed eighth with £3,681,580 while rivals Manchester City topped the rankings with £10,537,982.

Sir Alex, though, does not see fees reducing in the near future, let alone eradicated completely.

Sir Alex continued: “Once there's a transfer window, agents will make money. They are there and they are not going away I'm afraid. We'd like to see them go away but that won't happen."
