The Argentinian began his playing career at Newell's Old Boys, but only made one appearance for the club.
The plaudits he earned in Argentina earned him a move to prestigious European club Ajax, where he would first meet Erik ten Hag. Martinez enjoyed a very successful spell with Ajax which earned him a £47million transfer to Manchester United.
Martinez has also seen success on the international stage in his short career. He contributed to Argentina's success in the 2021 Copa America, playing alongside fellow Newells' native and seven-time Ballon d'Or winner Lionel Messi.
As it is for all players who move continents, Martinez transfer to Ajax was a journey into the unknown. But not for the Dutch giants who had followed his career in-depth for two years.
As well as the 2021 KNVB Cup, the Argentine won the Eredivisie twice. He was a part of a meagre defence that conceded only 23 goals in 34 games in the 2020/21 season.
The appointment of Ten Hag at Manchester United had many speculating there would be a reunion with Martinez.
The Old Trafford club eventually forked out £47m, plus £8.5 million in add-ons in July 2022 to bring Martinez to Manchester, as Ten Hag raided his old side for star names. Fellow Ajax alumni Anthony moved to United in August.
Ten Hag referred to Martinez as a warrior with fighting spirit who would bring a good form of aggressiveness to Manchester United's football. The manager also believes that Martinez will restore pride and bring a connection to fans that has been lacking.

Martinez is not the archetype of a British centre-half. His 5ft 9in stature has led to many comments and criticism in his time at the club.

However, the defender started to overcome the doubters at Old Trafford as the club managed to deliver an upturn in form with four straight wins.
Martinez has already gone toe-to-toe with even the most physical Premier League strikers, living up to the nickname 'The Butcher' which he gained at Ajax.
Martinez's net worth is believed to be around £31million, and he is reportedly on around £120,000 a week salary.
