Holloway launched his managerial career with home-town Bristol Rovers in 1996 and has so far taken charge of four clubs.
Having joined Bristol Rovers as a teenager, the midfielder returned to the club for the third time to combine playing with managing. He continued in the difficult dual role for three years, a spell which included an appearance in the Division Two play-offs.
Holloway finally retired as a player in 1999, after more than 400 matches for Rovers, and was appointed by Queens Park Rangers two years later.
After being unable to halt Rangers slide to relegation, he stayed on to rebuild and win promotion back to the second tier. Ian then established the club in the Championship before leaving Loftus Road suddenly after being linked with other clubs.
He re-emerged in June, 2006 as boss of Plymouth Argyle where he quickly established a rapport with players and supporters. After his first away win - 3-2 at Sunderland - he memorably offered to buy a drink for all the 700 Argyle fans who made the 800 mile round trip.
Holloway resigned to join Leicester City in November, 2007, becoming the first Foxes manager in over 50 tears to win his first league game - a 2-0 victory over Bristol City.
Having inherited a team threatened with relegation, he left the Walkers Stadium with good grace after narrowly failing to keep the club in the Championship.
In his first full season with Blackpool, Holloway remarkably guided Blackpool to the Barclays Premier League with a 3-2 play-off final victory over Cardiff City. The success saw The Seasiders return to the top flight of English football after a 39 year absence and Holloway became only the second Blackpool manager after Les Shannon to win promotion in his first full season.
Blackpool provided fantastic entertainment in the Premier League during the 2010/11 campaign and recorded notable results which included a league double of Liverpool. The club were relegated on the final day despite Blackpool amassing a notable 39 points.
Another excellent season followed in the Championship, as Holloway guided the club to the play-off final. Blackpool narrowly missed out on an instant return to the Premier League after a 2-1 to defeat to West Ham at Wembley.
However, the following campaign Holloway once again reached the Championship play-off final where his Crystal Palace side were victorious after defeating Watford 1-0 at Wembley to win a match that had been described as being worth £120m.
Following his appointment at Millwall in January 2014, Holloway went on to secure their Sky Bet Championship status for the 2014/15 season.
Holloway's four-club playing career also took in spells with Wimbledon, Brentford and QPR where he made over 150 appearances in five seasons.
