Jackett initially enjoyed little success as manager of Watford, finishing 13th in Division Two in 1996-7 (their lowest finish in nearly 20 years). He was then demoted to assistant manager in place of Graham Taylor.
After a period of time as assistant manager Jackett made the step up once more as he became the Swansea manager in April 2004. In his first season in charge they won promotion to League One and won the FAW Premier Cup. He then oversaw a successful second season with the club just missing out on back-to-back promotions after losing in the play-offs.
Jackett became Millwall manager in 2008 and he guided them to the League One Play-offs. But, once again, he suffered heartbreak after losing the final 3-2 against Scunthorpe. Once more they finished in the play-offs the following season, just missing out on automatic promotion.
This time they beat Swindon Town 1-0 to win promotion to The Championship. In the next three seasons he kept the club comfortably in the division, including a semi-final appearance in the FA Cup. He resigned today (7 May) from his role.
