Swansea City are on the brink of the permanent signing of Hoffenheim winger Gylfi Sigurdsson.

Sigurdsson's move will smash the club's record for a transfer fee, previously held by Danny Graham when he completed a £3.5million switch from Watford last summer.

"Swansea City can today confirm a transfer fee and personal terms have been agreed for Hoffenheim midfielder Gylfi Sigurdsson," said a statement.

"A club record offer of £6.8million has been accepted by the German club, and the 22-year-old is expected in Swansea later this week to undergo a medical before the move is confirmed.

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