Redknapp took over at Tottenham in October 2008 and had a good run with the side in the Champions League during his tenure.
Having arrived at the club when they were in a relegation battle early on in the 2008/09 season, it is fair to say that Harry Redknapp had left it in better health than he had found it in when he succeeded Juande Ramos.
There was a lot of speculation at the time that Redknapp could take over as the England manager in 2012, with BBC Sport reporting that he was among the favourites prior to the appointment of Roy Hodgson. This was while Tottenham were firmly in the thick of the title race but ended up sliding alarmingly. they managed to salvage fourth place in the closing stages of the season only to miss out on Champions League qualification because of Chelsea's success in the competition.
Overall it was a decent reign at White Hart Lane for Harry Redknapp. He guided them to safety in his first season before the side kicked on in his first full campaign in charge to qualify for the Champions League - where they reached the quarter-finals the following season. During this time he was presiding over Gareth Bale going on to the next level in terms of his performance.
He guided the side to the 2009 League Cup final and 2012 FA Cup semi-final - although if there was one thing his reign missed, it was silverware.
Following on from Redknapp's sacking, Spurs have had three managers. Villas-Boas lasted just under 18 months after narrowly missing out on Champions League football, and being at the club while Bale was sold with the money spent poorly. He was replaced by Tim Sherwood, whose reign was pretty brief before the current manager Mauricio Pochettino led them back into the Champions League with a third-place finish this season. However, it could have been so much more given their position in the title race.
Looking back, however, it does seem that Redknapp's reign at White Hart Lane was a significant one, despite the faults he may have had.
