Paul Pogba, the 30-year-old France midfielder, has been banned from football for four years due to doping.
What happened?
The ban was confirmed on Thursday, with Pogba stating he will appeal against the decision, claiming he would "never knowingly" dope.
Reaction from Massimiliano Allegri
Massimiliano Allegri, the Juventus manager, expressed his sadness at the loss of an extraordinary player, saying "football is losing an extraordinary player".
Allegri had the opportunity to work with Pogba during his first stint at Juventus, where they won the Serie A title in 2015 and 2016.
Background on Pogba's career
Pogba signed for Manchester United in a then-world record £89m deal after his successful spell at Juventus.
He returned to Juventus on a free transfer in 2022 but has struggled with injuries, making just one start and 11 substitute appearances.
What comes next?
Pogba was tested randomly after their first match of the season on 20 August, with the positive result confirmed by Italy's national anti-doping tribunal following testing of a second sample in October.
The anti-doping prosecutor's office requested a four-year suspension, which will run until August 2027, when Pogba will be 34.
Allegri sent Pogba a message on Thursday after the announcement of the ban but will not comment further on the case while "there is a procedure under way".
Pogba believes the verdict was "incorrect" and will appeal to the Court of Arbitration for Sport.
The 36-time Italian champions are currently second in Serie A, 12 points behind leaders Inter Milan, and have gone two seasons without a trophy under Allegri.
Juventus won five consecutive league titles under Allegri before he left the club in 2019, and he returned in 2021.
Pogba's ban is a significant blow to the team, with Allegri describing him as a "fantastic guy" and an extraordinary player.
The outcome of Pogba's appeal is still uncertain, but for now, he will have to wait until August 2027 to return to the pitch.
Pogba's career has been marked by successes, including winning the 2018 World Cup with France.
However, his recent spell at Juventus has been marred by injuries and now a doping ban.
The football world will be watching as Pogba's appeal unfolds, with many hoping for a resolution that will allow him to return to the sport he loves.
For now, Pogba's focus will be on clearing his name and overturning the ban, with the support of his manager and teammates.
The road ahead will be challenging, but Pogba has shown resilience and determination throughout his career.
Only time will tell what the future holds for this extraordinary player.
