Idrissa Gana Gueye joined Everton from Aston Villa on a four-year deal in August 2016.
The Senegal international spent one season with the Midlands club after forging a reputation as one of Ligue 1's finest young midfield players during seven years with Lille.
Gana has won more than 50 caps for his country and represented Senegal at the 2012 Olympic Games and 2018 World Cup.
He enjoyed an outstanding first season with Everton, his all-action and combative style of play in the heart of midfield immediately making him a firm fans’ favourite.
Such was his consistency, he was named runner-up in the Club's Player-of-the Season vote, narrowly missing out to top-scorer Romelu Lukaku.
Gana started every Premier League match aside from one - when he sat out a game at Chelsea in January through suspension - until his departure for the Africa Cup of Nations shortly after the turn of the year.
The N’Golo Kante comparisons were quick to come, too, a logical observation given the players’ similar physique and on-field attributes. A statistic often referenced was Gana’s tackling record and, by the season’s conclusion, he had topped that chart with 135 in the Premier League, seven more than Kante, who was crowned PFA Player of the Year.
Gana was in similarly tenacious form in 2017-18, when his total of 117 tackles was topped only by Wilfred Ndidi of Leicester City.
His maiden Everton strike against Sunderland in February 2017 was worth waiting for - a blockbuster of a finish after a precise cut-back from Seamus Coleman.
Gana has struck on three further occasions for the Blues. The first came in a Europa League first-leg qualifier against Hajduk Split in August 2017, with the player doing well to find space in the box and finish to put Everton 2-0 up.
Gana blasted in the Blues' second goal of a late-season 2-0 victory at Huddersfield Town, having been on target at Bournemouth in his side's final game of 2017. He committed himself to the Club for a further two years in February 2018 when he penned a deal to keep him at Goodison Park until at least summer 2022.
The 2018-19 season saw Gana sustain his exceptional form, establishing himself as an integral figure under new manager Marco Silva. Leicester's Ndidi, again, was the only Premier League player who won more tackles than the Everton man.
His consistently excellent performances were recognised by his Everton teammates at the end of the season, when he shared the Players' Player of the Season award with left-back Lucas Digne.
Gana made 134 appearances for Lille, having moved from Senegal's Diambars Academy as a teenager in 2008.
He contributed to the French side's title success in 2011 and established himself as a regular starter over the following four seasons, a period when Lille twice competed in the Champions League.
Gana's move to England in July 2015 brought 38 appearances in all competitions for Villa and, despite his side’s relegation, only Leicester’s Premier League-winning midfielder Kante made more interceptions and tackles combined across Europe’s top five leagues in 2015-16.
