Queens Park Rangers have appointed Harry Redknapp as manager on a two-and-a-half year contract.
The 65-year-old will watch his new team from the stands when Rangers play Manchester United at Old Trafford in the Premier League on Saturday.
Redknapp told QPR's website: "This was too good an opportunity to turn down.
"I'm delighted to be back in the managerial hot-seat at QPR. I can't wait to get to work and get the results necessary to kick-start our season."
Redknapp, who has been out of management for five months after being dismissed from his role at Tottenham in June, succeeds Mark Hughes, who was sacked on Friday with QPR bottom of the Premier League table, and without a win in their opening 12 games.
QPR chairman Tony Fernandes, believes Redknapp's appointment is a huge coup for the west London club.
"Harry was our number one target, the unanimous choice of the board and we're delighted we've been able to attract him to the club," said the Malaysian businessman.
"He has a proven track record in the Premier League and has all the characteristics we were looking for to get us out of the current situation we find ourselves in.
"His man-management skills are second to none and we have a manager with significant experience at the highest level of football, who can come in and immediately help deliver our objectives."
Rangers are four points adrift of 19th place - the same position Tottenham were in when Redknapp took charge at White Hart Lane in October 2008.
