Rabiot spent most of his career with PSG, making his debut with the first team in 2012 and winning eighteen major honours, including five Ligue 1 titles and a domestic treble in 2015–16 and 2017–18.

[6] In the club's pre-season he started in the penalty shootout defeat to Barcelona,[7] and, on 26 August, played his first game in Ligue 1, a 0–0 home draw against Bordeaux.

[8] Rabiot made his UEFA Champions League debut on 6 November 2012, playing during injury time in a 4–0 group stage home win over Dinamo Zagreb.

[11] Returning to PSG, Rabiot contributed with 46 matches and six goals[12][13] combined as the team won back-to-back domestic leagues from 2013 to 2015, but seemed to be on the verge of leaving the club as his mother Véronique acted as his main advisor during negotiations for a better contract.

[16] Rabiot scored his first goal in European competition on 25 November 2015 to open a 5–0 Champions League group win at Malmö,[17] and repeated the feat the following 9 March in a 2–1 victory over Chelsea at Stamford Bridge, putting PSG into the quarter-finals 4–2 on aggregate.

[23] The following January, after refusing to renew his contract and failing to appear for the first team since the previous month, the former midfielder was forced to train with the reserves.

[26] He made his debut for the club on 24 August, in the team's opening match of the 2019–20 Serie A season, coming on as a second-half substitute for Sami Khedira in a 1–0 away win over Parma.

[41][42] Rabiot made his senior debut for France on 15 November 2016 against Ivory Coast, starting and being replaced by Thomas Lemar after 78 minutes of the 0–0 friendly home draw, due to a hamstring injury.

A tall, strong, and elegant left-footed midfielder, who combines good technique with impressive physical qualities, Rabiot was regarded as a promising player in his youth.
