Villa 'need new players' - Emerypublished at 07:17 Greenwich Mean Time 3 February
Aston Villa are also close to signing Spain midfielder Marco Asensio on loan from Paris St-Germain.
On Saturday, Villa boss Unai Emery said the club "need new players" following their 2-0 defeat at relegation-threatened Wolves.
They have already signed Spanish full-back Andres Garcia from Levante and Netherlands forward Donyell Malen from Borussia Dortmund in January.
But Villa sold Colombia striker Jhon Duran to Saudi Pro League side Al-Nassr in a £71m deal and centre-back Diego Carlos to Fenerbahce for around £8.45m.
The Midlands club have made it through to the last 16 of the Champions League but are struggling to maintain their challenge to qualify for next season's competition.
They are eighth in the Premier League, four points off the top four.
