About Alexander
Alexander Sean Pablo Robertson is an Australian professional footballer who plays as a midfielder for Cardiff City. Born in Dundee, Scotland, on 17 April 2003, he developed through football in Australia and England before progressing through Manchester City’s academy and moving into senior football with loan spells at Ross County and Portsmouth. Robertson became Australia’s 630th men’s international and the first third-generation Socceroo in March 2023. Cardiff signed him permanently from Manchester City on 7 August 2024 on a four-year contract. Provider data lists him as active, with Cardiff and the midfielder role confirmed by the club.
Alexander Robertson was born in Dundee, Scotland, to an Australian father and Peruvian mother, and has strong Australian footballing connections through his family. His father, Mark Robertson, represented Australia, while his grandfather Alex Robertson was also associated with the national side. His uncle Gavin Rae played for Cardiff City between 2007 and 2011, giving Robertson an early connection with the club he later joined.
Robertson spent part of his childhood in Sydney and began developing in Australian junior football before moving into the English academy system. He was involved with Manchester United and subsequently Manchester City, where he progressed through the youth ranks and was regarded as a technically gifted central midfielder. His game is built around passing quality, movement, work rate and the ability to operate in central or more advanced midfield roles.
His first senior experience came on loan at Scottish club Ross County during the 2021–22 season. He later joined Portsmouth on loan for the 2023–24 campaign, gaining regular exposure in English senior football. Cardiff City then signed him permanently from Manchester City on 7 August 2024 for an undisclosed fee. The agreement was a four-year contract, taking him through June 2028 according to available contract reporting.
Robertson’s international pathway included youth representation for both Australia and England before he committed to the Australian senior team. He made his Socceroos debut against Ecuador on 24 March 2023 and became Australia’s 630th men’s international. Football Australia also recorded the historic significance of his debut: he became the first third-generation Socceroo. Robertson has described representing Australia as deeply meaningful and remained part of the national-team conversation after returning from a lengthy injury absence.
As at 24 August 2026, Cardiff City list Robertson in their first-team squad as a midfielder wearing number 18. The available 2026–27 provider and statistical listings identify him as active at Cardiff, while the club’s 2024–25 profile records 39 appearances, four goals and three assists during that campaign. Publicly available sources do not establish a complete, authoritative career statistical total across every club and competition, so no unsupported totals are included here.
Football Australia lists Robertson as Australia men’s international number 630, with his senior debut recorded in 2023. Cardiff City reported that he made 39 appearances, scored four goals and supplied three assists during the 2024–25 campaign. ESPN’s available 2025–26 listing records 16 starts, four substitute appearances, three goals and two assists; the listing should be treated as a published provider snapshot rather than a complete career total. His principal recognised distinction is becoming the first third-generation Socceroo.
Robertson’s defining international moment was his Australia debut against Ecuador on 24 March 2023, when he became the first third-generation Socceroo and Australia’s 630th men’s international. His first Cardiff goal came in the Carabao Cup in August 2024, according to Cardiff City. His permanent move from Manchester City to Cardiff City in August 2024 was another important career milestone.
