Swansea have confirmed the signing of Hoffenheim's Gylfi Sigurdsson for a club record £6.8m, but refuted speculation that Liverpool have made a renewed approach for manager Brendan Rodgers.

The 22-year-old, who spent the last five months of the season on loan with the Swans, will undergo a medical this week before the deal can be officially finalised, according to a statement from the club.

Sigurdsson scored seven goals in 18 Premier League appearances and said he was delighted to have agreed a deal to remain at the Liberty Stadium.

A club statement read: "The club are delighted to have agreed terms with both player and club following Sigurdsson's hugely successful loan spell last season."

Sigurdsson joined Hoffenheim from Reading in September 2010 and scored nine goals in 36 appearances before being loaned to Swansea in January.

Meanwhile, the club have also denied recent reports regarding Rodgers and Liverpool's interest in the Swans manager.

"We would like to clarify the speculation in the press surrounding our manager Brendan Rodgers," the club said.

"We would like to confirm that there has been no contact from Liverpool and nothing has changed since our previous statement on the issue."

Wigan are expected to hold a press conference on Tuesday in which Roberto Martinez will announce whether or not he will stay at the club. The Spaniard met Liverpool's owners in Miami on Thursday to discuss the managerial vacancy.

And Wigan chairman Dave Whelan revealed on Friday that Martinez had received an offer from Liverpool's principal owner John W. Henry.

"[He] had a very constructive meeting with the owner of Liverpool," Whelan is quoted in Metro. "They're going to talk again on Tuesday.

"They've made Roberto an offer and he has agreed to consider it."
