He has previously managed AFC Bournemouth, West Ham United, Portsmouth, Southampton, Tottenham Hotspur, Queens Park Rangers and Birmingham City.

[10] At age eleven, while Redknapp was playing for East London Schools football, he was spotted by Dickie Walker, a Tottenham Hotspur scout.

From there, Redknapp grew in the Tottenham youth ranks playing at Cheshunt, meeting the likes of Bill Nicholson, Dave Mackay and Danny Blanchflower.

[11] In a 2008 interview, Redknapp stated as part of a tribute to Tom Finney, "I was a big Arsenal fan as a kid and I remember seeing him play against Tommy Docherty one night.

[16][3] Redknapp then made five appearances during the 1977 season as they finished third in the Pacific Conference, Western Division, before losing out in Soccer Bowl '77 to Pelé's New York Cosmos, 2–1.

[19] During the 1978 season, Redknapp helped Seattle to a third-place finish in the National Conference, Western Division, before they lost in the first round of the playoffs, again to the New York Cosmos.

In his final year in Seattle, he helped them to another third-place finish in the National Conference, Western Division, but this time they failed to qualify for the playoffs.

At the beginning of the 1982–83 season, Redknapp took up his first major coaching role as assistant manager to David Webb at Bournemouth, six years after leaving the club as a player.

Redknapp applied for the manager's job when Webb moved to Torquay United partway through that season, but was overlooked in favour of Don Megson.

Bournemouth were in 13th position on 3 March, but injuries which depleted the squad, combined with a catastrophic loss of form, meant they won only one more match that season, and were relegated on 5 May after a 1–0 defeat at Dean Court against Leeds United.

[27] Though he made a full recovery, apart from losing his sense of smell and gaining a facial tic, he eventually quit Bournemouth at the end of the 1991–92 season.

However, in August 1994, the club board of directors opted to turn control of the team over to Redknapp and move Bonds into an administrative role.

For some time, it was unconfirmed whether he resigned or was sacked but Redknapp shed new light on the true circumstances in October 2007: The chairman Terry Brown had offered me a new four-year contract.

Redknapp remained in charge for the 2005–06 Championship season but was unable to establish consistency needed to make Southampton promotion contenders.

[36] After being repeatedly linked with a return to Portsmouth after they sacked Alain Perrin, Redknapp resigned as Southampton's manager in early December 2005.

[38] In January 2008, it emerged through the media that Redknapp was offered the vacant manager's job at Newcastle United following the sacking of Sam Allardyce.

As this event took place two days after his departure for Tottenham Hotspur, he received a mixed reception from the Portsmouth fans, despite having led the club to a long-awaited trophy in the 2008 FA Cup.

[44] Long-serving Chelsea goalkeeper Carlo Cudicini also joined on a free transfer; former Spurs player Pascal Chimbonda returned to White Hart Lane from Sunderland for a fee in the region of £3 million; and Robbie Keane, who like Chimbonda and Defoe had only left Spurs within the last year, re-joined after an unsuccessful spell at Liverpool for an initial fee of £12 million.

Beginning with four consecutive wins,[51] Spurs went on to finish in fourth place with 70 points, therefore gaining the chance to qualify for the UEFA Champions League via a play-off.

[61] On 24 November 2012, Redknapp, who had been working at former club Bournemouth in an advisory role,[62] was appointed as manager of Queens Park Rangers,[63] taking over from Mark Hughes, whose contract was terminated the previous day.

[66] Redknapp earned his first win as QPR manager, and the club's first Premier League victory of the 2012–13 season, on 15 December after defeating Fulham 2–1 at Loftus Road.

[68] His first match against Tottenham since being sacked by the North London club came on 12 January 2013, with Redknapp leading QPR to a 0–0 draw at Loftus Road.

[70] After a single season in the Championship, Redknapp managed QPR to a 1–0 victory in the Play-off Final against Derby County on 24 May 2014 at Wembley Stadium, returning the club to the Premier League.

[76] In March 2016, Redknapp was appointed manager of the Jordan national team alongside his former assistant, Kevin Bond, for the country's next two qualifying matches for the 2018 FIFA World Cup.

[81] The final two matches of the season saw Redknapp's team beat Huddersfield Town 2–0,[82] followed by a 1–0 away win at Bristol City, allowing Birmingham to escape any threat of relegation.

[94] In October 2017, following his departure from Birmingham City, Redknapp briefly joined League Two club Yeovil Town in a voluntary advisory role to manager Darren Way.

The England team was captained by former lioness, Jill Scott, and the match was hosted at Stamford Bridge stadium against a World XI, with proceeds going to charity.

[102] On 19 September 2006, Redknapp was shown on camera by BBC Panorama taking part in what appeared to be an interest in approaching a player in a manner forbidden by FA rules.

[103] In the final report of the Stevens inquiry, published in June 2007, the only criticism of Redknapp concerned his ownership of a racehorse named Double Fantasy thought to have been given to him by the agent Willie McKay, which has aroused some suspicion.

[122] His nephew is former England midfielder Frank Lampard, Jr. whose parents are Sandra's late twin sister, Patricia, and Harry's former teammate and managerial assistant Frank Lampard, Sr.[123] Redknapp and his wife are the fundraising presidents for the Southampton-based charity Leukaemia Busters, a role they took over in 2004 previously held by former cricketer David Gower and his wife Thorunn.
