Anthony Martial’s career has taken a new turn, with the Frenchman set to head to Mexico.After just one year in Greece with AEK Athens, the former Manchester United striker is joining Monterrey, according to transfer journalist Fabrizio Romano.Martial’s time with Athens didn’t last very long, and he’s getting moved onNurPhoto via GettyHe reports a deal for the forward to join the Mexican side is now agreed.At the moment, it isn’t clear if there is a fee, but Monterrey were desperate to add another attacker before the close of their transfer window on Friday.It is also unclear how much Martial will earn after signing a lucrative three-year deal with AEK in 2024.The contract made him the highest-paid player in the club’s history, earning around £8.3million.But that looks to be over, and Martial will join up with Real Madrid legend Sergio Ramos.Another former Real Madrid player in Sergio Canales is also there.Martial was linked with a move to Pumas, where he would have got to link up with ex-Arsenal star Aaron Ramsey.But instead, it is Monterrey for Martial.The move comes as a huge surprise, given Martial actually enjoyed a decent season with nine goals in 23 games across all competitions.However, new manager Marko Nikolic doesn’t have the 29-year-old in his plans, leaving him out of AEK’s Conference League squad.Ramos is Monterrey’s biggest player by some distanceGettyWhat happened to Martial?When Man United paid a world-record fee for a teenager in 2015 from Monaco, the expectation was that they had a signed potentially world-class forward.There was even a Ballon d’Or clause inserted into the contract in case Martial won the prestigious award.In the end, he made 317 appearances for the Red Devils, scoring 90 goals and providing 54 assists.In the Premier League, it was 209 appearances and 63 goals with 33 assists.They represent respectable statistics, but injuries were the main issues for the striker.Martial suffered constant injury issues, and by the end, he was a bit-part player at Old TraffordGettyWhile in Manchester, Transfermarkt report Martial had 22 separate injuries.He still left the club with six trophies, including the Europa League.And when he left after nine years, he penned an emotional goodbye to Man United fans.He said: “Dear Manchester United fans.“It’s with great emotion that I write to you today to say goodbye.“After nine incredible years at the club, the time has come for me to turn a new page in my career.“Since I arrived in 2015, I have had the immense honour of wearing this shirt and playing in front of you, the best supporters in the world! You have been an unwavering support, through the good times and the difficult. Your passion and loyalty have been a constant source of motivation for me. “I’d like to thank you from the bottom of my heart for everything you’ve done for me. Your songs, your encouragement and your love for the club are memories that will remain engraved in my heart forever.“I would also like to express my gratitude to all my team-mates, technical staff and all the members of the club I have met during my 9 years here. I am proud to have been able to share these experiences with you.“Manchester United will always be in my heart. This club has left its mark on my career and offered me an incredible opportunity to play in front of you. I’m leaving to take on new challenges, I’ll always be a Red Devil and I’ll continue to follow the club’s results with passion.“Thank you again for everything, and see you soon. With all my affection, Anthony Martial.”His fall from grace is quite startling, given he isn’t into his 30s yet.But there was no interest in him from teams in Europe during the transfer window, and he at least has a career lifeline in Mexico.
