Luis Suarez will reportedly have to submit a formal written transfer request if he wishes to make a summer exit from Liverpool, who value their prized asset at £50m.
The Uruguayan striker has continually suggested to the media that he would like to leave the Reds for Real Madrid following a series of disciplinary problems that have damaged his reputation in England.
However, he has yet to inform the Anfield hierarchy of his plans to quit the Premier League, and the Daily Mail reports that Liverpool want official confirmation of Suarez's intentions as soon as possible.
Manager Brendan Rodgers plans to do his transfer business early this summer and has already captured experienced defender Kolo Toure as a free agent.
The potential sale of Suarez would help fund moves for Celta Vigo striker Iago Aspas, Sevilla winger Luis Alberto and Sunderland goalkeeper Simon Mignolet, according to the same newspaper.
