Redknapp is an irrepressible character who has worked in management almost non-stop for over a quarter of a century.
Aside from two brief breaks from the game, Redknapp's longevity stretches back to his appointment by Bournemouth in 1982.
He is a member of the exclusive 1,000 game club, having gone on to take charge of West Ham, Portsmouth - twice - Southampton, Spurs and now QPR.
The former winger, who had long playing spells with West Ham and Bournemouth, was also a popular manager with both those clubs. He led Bournemouth to the Division Three title on the back of a record 97 points in 1987, having earlier inspired one of the FA Cup's greatest shocks - a defeat of Manchester United.
Redknapp then embarked on a seven-year reign at Upton Park where he took West Ham into Europe.
After keeping the Hammers in the top flight, Harry achieved finishes of tenth, eighth and then fifth in 1999. During that era, he helped nurture future England stars Rio Ferdinand, Joe Cole, Frank Lampard and Michael Carrick.
Following his sudden departure from Upton Park, Redknapp propelled Portsmouth into the Premier League as Division One champions in 2003.
He returned to Fratton Park following a fleeting, unsuccessful dalliance with south coast neighbours Southampton. Redknapp's second link-up with Pompey chairman Milan Mandaric proved even more prosperous than the first.
After avoiding relegation, Portsmouth achieved their highest placing since the 1950s by climbing to seventh in 2007. The following season, they were were FA Cup winners after reaching the final for the first time in 69 years. It also meant the club were in Europe for the first time.
Redknapp once "retired" from football after quitting his first managerial job at Bournemouth in 1992. Sixteen years later, he accepted his greatest of many challenges when leaving Fratton Park for White Hart Lane.
Tottenham had two points from the first eight games in the league when Redknapp took charge but he led Spurs to an eighth place finish as well as the Carling Cup Final in 2009.
The following season Redknapp became the first English manager to be named Barclays Premier League Manager of the Year after leading Tottenham to fourth place ensuring Champions League football for 2010/11.
Following their qualification to the Champions League, Redknapp would set another record by becoming the first English manager to reach the quarter finals of the competition. Their incredible journey included Spurs topping the group stages over Inter Milan, Werder Bremen and FC Twente, all of whom won their respective leagues in the previous season. Redknapp's side also had another fantastic campaign in the Barclays Premier League by finishing fifth, thereby qualifying for the Europa league.
Another successful season followed in 2011/12 and Redknapp was awarded the manager of the month awards for both September and November. Harry guided Spurs to a 4th place finish in the Barclays Premier League and the club also reached The FA Cup semi-final.
He was later appointed manager at Loftus Road during the 2012/13 season. Redknapp secured the Club's immediate return to the Barclays Premier League after a play-off final victory over Derby in 2013/14.
