Sevilla have approached Liverpool about signing defender Mamadou Sakho, according to Sky sources.
Liverpool will only let the centre back leave Anfield on a permanent deal and they value him at more than £20m.
Sakho has fallen out of favour with manager Jurgen Klopp and has been playing for Liverpool's Under-23 side.
The French international joined Liverpool for £18m from Paris Saint-Germain in September 2013 but has not made a first-team appearance this season.
Sakho was sent home from Liverpool's pre-season tour of the United States by Klopp after turning up late for their flight to America and interrupting an interview the Reds boss was conducting.

Liverpool accepted a loan offer for Sakho from Stoke at the start of the season but he turned the move down.
