Former Liverpool club-record signing Naby Keita is now worth almost £40 million less than the Reds paid to bring him to Anfield five years ago.
The Guinea international ended a mixed spell at Liverpool when he left the club following the expiry of his contract in the summer.
Keita's time at the club was dogged by injury problems, after the Reds shelled out an initial fee of £47 million to sign him from RB Leipzig in 2018.

The midfielder was one of the first marquee signings of the Jurgen Klopp, and big things were expected of him after he was involved in 26 Bundesliga goals across his two seasons at the club.
But despite flashes of brilliance, injuries and mixed form stopped Keita from fulfilling his potential at Anfield. However, he did lift a Premier League and Champions League crown while at the club.
His last game for the Reds came in a 0-0 draw against Crystal Palace in February - a game in which the 28-year-old was substituted at half-time.

He was then struck down by injury, and although he was named on the bench for the second leg of Liverpool's Champions League last 16 tie against Real Madrid, would never make another appearance for the club after suffering a season-ending injury.
Keita joined Bundesliga side Werder Bremen before the start of this season, but suffered a knock in the warm-up ahead of his debut in pre-season.
Injury problems have continued to affect the Guinea midfielder, although he has returned to play in each of Bremen's last three games.
But his lack of availability in recent seasons has caused his transfer value to drop significantly.

As per Transfermarkt, Keita's value now stands at just €9 million (£7.8 million) - almost £40 million less than Liverpool initially bought him for.
Speaking to GiveMeSport earlier this month, Redmen TV presenter Paul Machin described Keita as 'the biggest flop of the Klopp era' at Anfield.
And despite his talents, things just didn't quite work out for the midfielder at Liverpool.
