Ljungberg's ill-fated spell at West Ham is believed to have cost the club around £13 million in transfer fees and wages and Curbs has already this week denied that he was behind the mess.
"Ever since I've been at the club, all the transfer negotiations, fees and contracts have been done by first Eggert Magnusson and now Scott Duxbury," said Curbs.
"He's the person to go and see. I just recommend."
In an interview with the Sun co-owner Asgeir Fridgeirsson denied that the management were in charge of recruiting players pointing the finger of blame straight back at Curbs.
"It's the manager and his management team who are responsible for paying out the player's salary," he said.
"It is their judgment about how to use the money they paid to Ljungberg in a wiser way.
"We all have our personal opinion about Freddie and his efforts for this club."
