5. Harry Redknapp
Having replaced Harry Redknapp as Spurs boss in July of 2012, the outgoing Portuguese boss earned himself the highest win percentage of any Spurs manager in the Premier League era, as well as earning the highest points total for the Lilywhites in any season of the same period - 72 points last season. That said, he still failed to emulate the relative success of the former West Ham United manager. Redknapp took Spurs to the quarter finals of the Champions League and saw the club finish fourth the following season - but heartbreakingly fail to qualify for Europe's elite competition again by virtue of the fact that Chelsea won the competition whilst finishing fifth in the Premier League. Redknapp is now manager of Championship club Queens Park Rangers - a huge fall from grace from the man who was apparently destined to be named as the England boss prior to Roy Hodgson's appointment - and if Spurs came calling again it would be hard for him to say no to them. That said, it's extremely unlikely that Daniel Levy would go back in for the renowned wheeler-dealer and Spurs fans would probably not see it as progressive to bring back a previous manager. However, I certainly wouldn't 100% rule it out as a possibility.
