They have accused Brendan Rodgers, who left for Liverpool this summer, of reneging on a promise not to bid for their players this year.
“Swansea City 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.
“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 duty.”
