Rix played for Arsenal for thirteen years, then Brentford (on loan), Caen, Le Havre, Dundee and Chelsea.
Rix then managed Chelsea (as caretaker), Portsmouth, Oxford United, Heart of Midlothian, Central and AFC Portchester.
Together with Liam Brady, he formed part of an impressive attacking midfield, which helped Arsenal to three successive FA Cup finals between 1978 and 1980.
Arsenal won the 1986-87 League Cup; Rix was not part of the squad for the final against Liverpool but he contributed three appearances en route.
[5][3][4] A series of injuries to his achilles tendon kept Rix out of the team in the mid-1980s, and he lost his starting place in the side to Martin Hayes.
During an injury crisis, he briefly enlisted as a player for the club, playing a solitary Premier League match in May 1995 against his old side Arsenal.
He won the FA Cup again in 2000, before leaving the club, after a brief spell as caretaker manager following Vialli's sacking by Ken Bates.
In November 2005, after speculation linking him with the manager's job at Scottish Premier League club Heart of Midlothian, it was confirmed that Rix would take over at Tynecastle.
[12] On 13 August 2012, Rix was named the first manager of Central FC,[13] which was a newly formed club founded by former Trinidad and Tobago international football player Brent Sancho, that competed in the TT Pro League.
[20] He was placed on the sex offender registry for ten years and banned by the FA from working with youth players under the age of 16.
[22] In 2018, Rix, along with assistant manager Gwyn Williams, was accused of racism and physical assault by several Chelsea trainees who were of school age at the time.
