Clément Nicolas Laurent Lenglet (born 17 June 1995) is a French professional footballer who plays as a centre-back for La Liga club Atlético Madrid, on loan from Barcelona.

[4][5] He made his Ligue 2 debut with Nancy on 27 September 2013 in a goalless home draw against AC Arles-Avignon entering the field after 32 minutes for Rémi Walter.

[10] He made his debut for the Andalusians eight days later in a 3–3 home draw with Real Madrid in the last 16 of the 2016–17 Copa del Rey (6–3 aggregate loss).

[11] On 15 January he made his league debut against the same opponents in a 2–1 win at the Ramón Sánchez Pizjuán Stadium that ended their 40-match unbeaten run in all competitions.

[13] He scored his first goal in European competition on 1 November, heading Éver Banega's cross to open a 2–1 home win against Spartak Moscow in the UEFA Champions League group stage.

[14] Having been part of the Sevilla side that kept a clean sheet against Manchester United in the round of 16 first leg, ESPN put Lenglet into their Champions League Best XI.

[18] Lenglet scored his first Champions League goal for the club on 8 August 2020, with a 10th minute header in a 3–1 victory at home against Napoli in Barcelona's round of 16 second leg match.

[27] On 21 May 2019, Lenglet was called up to the French senior team by Didier Deschamps for a friendly match against Bolivia, and for two UEFA Euro 2020 qualifying games against Andorra and Turkey, all of them to be held in the first half of June 2019.

France unexpectedly lost on penalties after a 3–3 draw, with Lenglet widely blamed for the first goal, in which Haris Seferovic beat him to a header.
