Swansea City have expressed their anger at Liverpool's million approach for their midfielder Joe Allen.

According to Sky Sports, former Swansea manager Brendan Rodgers, now with Liverpool, was confident he could bring the Welshman Allen with him to Anfield. The Northern Irish manager confirmed his interest in Allen, who is representing Team GB at the Olympics, last week.

Swansea are annoyed by these talks, as they claim Liverpool agreed not to make approaches for their players until 12 months after Rodgers's departure.

"Swansea can confirm that Liverpool have expressed an interest in Joe Allen, despite a written agreement with Liverpool not to approach any players within the 12-month period of former manager Brendan Rodgers leaving for Anfield," a Swansea spokesman said on the club's website. "There has also been interest from other clubs regarding his possible availability and the club is due to speak to Joe, as originally planned, about the situation when he returns from GB (Olympic) duty.

"The club is not prepared to release any details on whether any formal bids have been made at this stage or details of Joe's contract, which are private and confidential. The club is extremely disappointed that speculation regarding certain aspects of his contract have been released to the media by parties outside the club."

Swansea are not interested in selling their players, after they finished 11th in their first season in the Premier League following promotion from the Championship.

The spokesman added: "Fortunately the club is in a financial position where it does not need to sell any of its players and will continue to work in the best interests of its supporters, who are our priority, and the club to provide new manager Michael Laudrup with the best opportunity to be successful in the forthcoming Premier League campaign."

Liverpool open their new Premier League campaign away to West Brom, while Swansea face Queens Park Rangers on the road.
