http://news.bbc.co.uk/sport2/hi/football/7691457.stmTottenham Hotspur have sacked coach Juande Ramos and sporting director Damien Comolli and are set to appoint Portsmouth boss Harry Redknapp.
Spurs have agreed a compensation package of £5m with Portsmouth, according to the 61-year-old Redknapp.
Tottenham also axed first team coaches Gus Poyet and Marcos Alvarez following their worst ever start to a season.
"It's a big opportunity for me to manage a big club before I retire," said Redknapp.
Spurs are four points adrift at the bottom of the Premier League after taking just two points from eight matches this season. They also lost to Udinese in the Uefa Cup on Thursday.
Redknapp revealed Spurs contacted Portsmouth on Friday morning, and after discussions between Tottenham chairman Daniel Levy and Pompey chief executive Peter Storrie, it was agreed he could talk to the London club.
"I love Portsmouth and I loved my time there, we had some fantastic success and I'd never been happier," said Redknapp.
"But it's a great deal for Portsmouth, £5m for me, and it's a chance for me to get on and see what I can do.
"Once Tottenham came in and once the offer was made it was difficult for the club to turn down a £5m offer for a manager.
"The club were pleased to take it and hopefully people will remember what I've done there."
Redknapp expects the official announcement to come from White Hart Lane on Sunday morning.
"It will all be sorted out and by tomorrow morning I should be in place," he said.
Clive Allen, development squad coach, and Alex Inglethorpe, youth team manager will take charge of Sunday's game against Bolton, while Redknapp expects to be at White Hart Lane to address the players before the match.
"I know as much about Tottenham as anyone," said Redknapp. "I've followed the club for years and years.
"They've been on an horrendous run of games and we've got to get cracking and turn it around as quick as we can.
"We need a little bit more strength and aggression about the team if we're going to survive."
In January, Redknapp held talks with Newcastle to succeed Sam Allardyce as manager but eventually rejected the offer.
Redknapp spent most of his playing career with West Ham and Bournemouth and went on to manage both clubs before taking charge of Portsmouth in 2002, guiding the club into the Premier League within 14 months as First Division champions.
He left Fratton Park for Pompey's bitter south coast rivals Southampton in 2004 but returned in December 2005.
Then, after dramatically saving Pompey from the drop with an unbelievable final 10-game run, Redknapp steered them to a best-ever Premier League finish of ninth in 2006/07.
They bettered that by a place in 2007/08, and won the FA Cup against Cardiff, qualifying for their first journey into Uefa Cup football.
The 54-year-old Ramos joined Spurs from Sevilla on 27 October 2007 after Dutchman Martin Jol was sacked.
The Spaniard enjoyed back-to-back Uefa Cup triumphs with Sevilla and guided Tottenham to February's League Cup final where they beat Chelsea 2-1 for the club's first trophy since 1999.
However, several first-choice players left in the summer, notably Bulgaria striker Dimitar Berbatov to Manchester United and Robbie Keane to Liverpool.
England striker Jermain Defoe was also sold last January to Redknapp's Portsmouth.
Tottenham splashed out about £60m on the likes of Croatia midfielder Luka Modric, England winger David Bentley, Russia striker Roman Pavlyuchenko and Brazilian goalkeeper Heurelho Gomes.
