Former France and Real Madrid center back Raphael Varane announced his retirement on Wednesday, ending a career that included a World Cup title and a big haul of club trophies.

The 31-year-old Varane signed with promoted Serie A club Como in July but injured his knee during his only appearance with the club — an Italian Cup match against Sampdoria last month.

“In my career I have taken on many challenges, rose to occasion after occasion, almost all of it was supposed to be impossible,” Varane wrote on Instagram. “Reflecting on these moments, it is with immense pride and a feeling of fulfillment that I am announcing my retirement from the game that we all love.”

Varane was arguably the tournament’s standout defender when France won the 2018 World Cup in Russia, where he scored the most important of his five international goals with a header against Uruguay in the quarterfinals.

An elegant, ball-playing defender with excellent positional sense thanks to his quick reading of the game, Varane formed a solid center back pairing with Samuel Umtiti in that tournament.

He also helped Madrid to four Champions League titles and three Spanish league trophies.

He moved to Manchester United in 2021 but was restricted to 95 appearances in his three seasons in England — mainly because of injuries.

Varane began his career at Lens.

“From Lens to Madrid to Manchester, and playing for our national team. I have defended every badge with everything I have, and loved every minute of the journey,” Varane said. “I have no regrets, I wouldn’t change a thing. I have won more than I could have even dreamed of."

Varane had already retired from France's national team, a few months after the World Cup final defeat to Argentina in 2022. During that match, his 93rd for Les Bleus after making his debut in 2013, he fell to the ground exhausted deep into extra time.

Over the years he became one of the main leaders in the France team under coach Didier Deschamps, along with goalkeeper Hugo Lloris, midfielder Paul Pogba and forward Antoine Griezmann.

“Knowing him, I know that this decision, which is always difficult to take, came after mature reflection,” Deschamps said. “It's therefore the right decision, which we must respect. Speed, vision, technique, mental strength, Raphaël had all the right qualities to achieve the magnificent career that was his.”

Varane played a total of 22 matches in major tournaments.

“I will remember a player who was focused on others and on the team. He had a perfect rapport with captain Hugo Lloris,” Deschamps said. “In the national team, and wherever he went, he always left the impression of being a great professional.”

Varane said he would remain at Como: “Just without using my boots and shin pads. Something I am looking forward to sharing more about soon.”

Como got its first Serie A victory in more than 21 years when coach Cesc Fabregas’ team won 3-2 at Atalanta on Tuesday.
