Fulham are in advanced talks to sign Villarreal centre-back Jorge Cuenca.
The Cottagers believe they can secure the 24-year-old for as little as £6.7million.
Fulham manager Marco Silva is insistent on the club signing two centre-backs this summer, with Tosin Adarabioyo having joined Chelsea as a free agent and Tim Ream in talks to join Charlotte FC in the MLS.
Cuenca, formerly of Barcelona, became a regular for Villareal last season.
Meanwhile, Fulham are set to announce the signing of Emile Smith Rowe from Arsenal.
The midfielder will join for £27m plus £7m in add-ons in a club-record deal for Fulham.
