In June 2016, Koeman left Southampton to join Everton and Claude Puel replaced him on a three-year contract. The club were eliminated in the group stage of the Europa League but were more successful in the EFL Cup, where they lost 3–2 in the final to Manchester United. The club ended the 2016–17 season in eighth. During the summer, Puel was replaced as manager by Argentine coach Mauricio Pellegrino, previously of Deportivo Alavés. In mid-season, the club sold Dutch defender Virgil van Dijk to Liverpool for an estimated £75 million, Southampton's record sale and a world record for his position. Pellegrino was sacked in March 2018 with the team 1 point above the relegation zone, and his replacement, former player, Mark Hughes, guided the club to a 17th-place finish, avoiding relegation on the last day of the season. Hughes signed a new contract at the end of the season but a poor start to the following season led to him being sacked in December 2018 with the team in 18th place. He was replaced with former RB Leipzig boss Ralph Hasenhüttl, who steered the club away from relegation to finish 16th.
