Liverpool will demand £20m for defender Mamadou Sakho if he moves during the January transfer window.

The France international signed a new long-term deal at Anfield in 2015.

But he has not played for the first team since April because of off-field issues.

The 26 year old was sent home from Liverpool's pre-season tour of the United States by manager Jurgen Klopp as a disciplinary measure.
