Charlton boss Alan Curbishley would like to see the transfer window expanded to eight weeks so clubs can have enough time to land their targets.
The system was put in place in England by the world’s governing body FIFA for the 2002-03 season, and restricts teams to just two periods of activity in the market for new players – either during the close-season or for a month at the start of the year.
There have been just a few moves so far since the opening of the 2005 window - Jean-Alain Boumsong, James Beattie and Dean Ashton three of the men to make big-money switches during so far.
However, the Charlton manager – who has a transfer kitty of around £3million - believes the complications which come with locating your targets and finalising deals means four weeks is “just not long enough”.
Curbishley said: “I don’t think this transfer window has been a success. It’s very difficult to get anything done in a month.
“It’s just not a long enough period of time.
“You can tell that people aren’t happy with it because there isn’t much business happening.
“They should consider extending it to eight weeks. That would make things a bit easier for everyone concerned.”
Despite having money to spend and being been linked with moves for Ipswich striker Darren Bent and Nottingham Forest defender Michael Dawson, Curbishley believes clubs like Charlton are often held to ransom as they go in search of completing the acquisition of new talent during the window.
“Another problem with the current system is that the prices for players get inflated because there’s only a short period of time in which to do anything,” he reflected.
The Charlton manager, though, insisted he was not about to let anybody leave The Valley this month.
“I’m looking strengthen in all areas of the pitch and I’m hopeful of people coming in before the window closes,” said Curbishley.
“But there definitely won’t be anybody going out – I don’t want to sell anyone.
“That’s another reason why it’s hard to do business. Everyone wants to buy, but nobody wants to sell. It’s a tough situation.”
