Here, Press Association Sport looks at the 70-year-old's management career.
Redknapp's first steps in management came at Bournemouth, where he made more than 100 appearances as a player
He led the Cherries to promotion to the second tier as champions of the old Division Three in 1987, having also won the Football League Trophy in 1984
Bournemouth were relegated from Division Two in 1990 before Redknapp resigned at the end of the 1991-92 campaign.
West Ham 1994-2001
After joining the Hammers as assistant to Billy Bonds, Redknapp took the hot seat in 1994 with the club about to start their second season in the recently-formed Premiership
He brought through numerous academy players during his time at Upton Park, including Frank Lampard, Joe Cole, Rio Ferdinand and Michael Carrick, as well as reinvigorating the career of Paolo Di Canio after controversially signing the Italian from Sheffield Wednesday
Redknapp won the Intertoto Cup in 1999 after leading United to fifth place in the top flight the previous season
Redknapp initially arrived at Fratton Park as director of football before replacing Graham Rix as manager
He guided Pompey to the top flight in 2003, winning the old Division One title with a free-flowing style of football led by veteran midfielder Paul Merson
After keeping the south coast club in the Premier League, Redknapp resigned in November 2004 following a dispute with owner Milan Mandaric
A few weeks after departing Pompey, Redknapp made the controversial decision to join their bitter rivals Southampton
His task was to keep the Saints in the top flight but he failed to do so before struggling to turn them into promotion contenders the following season and subsequently resigning in December 2005.
Redknapp immediately returned to Pompey after leaving St Mary's and would go on to enjoy another successful spell at Fratton Park
He saved them from relegation to the Championship in his first season and guided the club to their second FA Cup success with victory over Cardiff in the 2008 final at Wembley
The cup win earned Portsmouth qualification to the following season's UEFA Cup, although Redknapp only enjoyed a brief taste of European competition on the south coast before moving on again.
A four-year spell with Spurs is perhaps Redknapp's most high-profile managerial role to date
During his time at White Hart Lane, he brought Champions League football to north-east London and assembled an attacking, entertaining team which defeated Inter and AC Milan before being knocked out by Real Madrid
Redknapp also helped develop the career of Gareth Bale, turning the Wales international into an attacking player, which ultimately led to his big money move to Madrid.
Redknapp was not out of work long following his sacking by Spurs as he moved across London to take charge at Loftus Road
Rangers were relegated from the Premier League in his second season in charge but they achieved an immediate return following Bobby Zamora's dramatic late winner in the 2014 Championship play-off final
Redknapp resigned part-way through the next season - citing a knee operation as one of the reasons - before the Hoops slipped back into the second tier
Redknapp briefly took charge of Jordan's national team last year
He oversaw two qualifying matches for the 2018 World Cup in Qatar, thrashing Bangladesh 8-0 in the first before losing 5-1 to Australia in Sydney.
