Liverpool have demanded a sell-on clause in their deal with Reading for Tiago Ilori.
The two clubs have agreed a £3.75m fee for the player.
Ilori joined Liverpool from Sporting Lisbon in 2013 but hasn't made much of an impression at Anfield.
The Daily Mail says along with the £3.75m fee, Liverpool have inserted a 25 per cent sell-on clause in the deal.
They add the transfer is expected to go through in the week ahead.
