Adama Soumaoro would be a strong summer addition by Everton, strengthening their defence significantly in the process.
According to French outlet La Voix du Nord, the Toffees are eyeing up a move for the LOSC Lille captain, who would cost somewhere in the region of €12-15 million.
Soumaoro impressed for the Ligue 1 side last season, leading them to a second-place finish behind Paris Saint-Germain.
A move to the Premier League is now being mooted, with Everton joined by Crystal Palace in showing an interest.
Lazio have also been linked with the 27-year-old, who rose through Lille’s academy to become a key man.
Marco Silva is looking to turn Everton into a top-six club and acquiring Soumaoro’s service would be a positive step in the right direction.
Any good side is built on solid foundations and Everton have lacked a true leader at the back since Phil Jagielka in his prime.
There are good defensive options for Silva, from Michael Keane to Yerry Mina, but Soumaoro would still arguably be an upgrade.
A move isn’t necessarily close to happening – Palace could provide stern competition – but it is one that Everton should be focused on getting over the line.
5 of Everton's best Premier League centre-backs
Jagielka was a stalwart for Everton over 12 seasons, making 385 appearances.
He has moved back to former club Sheffield United to see out his excellent career.
Lescott thrived at left-back for a period, but he was at his best at centre-back for Everton.
The former England international was an imposing figure with an eye for goal, scoring 17 goals in 143 matches.
Weir was a popular figure at Goodison Park over an eight-year period between 1999 and 2007.
A key man for Scotland at the same time, he was a consistent presence at the heart of the defence.
A defensive rock who was superb at his best, Distin was another great servant to Everton.
In total, the Frenchman spent six years at the club, winning the Toffees’ Player of the Year award in 2011/12.
Stubbs, like Weir, was another no-nonsense figure who rarely let Everton down.
He enjoyed two spells at Goodison Park – 2001-2005 and 2006-2008 – excelling for his boyhood team.
