The Spurs manager was the subject of frenzied speculation on internet sites which saw bookmakers slash odds on him becoming the first Barclays Premier League manager to lose his job this season.

At one point they tumbled from 50-1 to evens, despite Redknapp having led Tottenham to their best start for 50 years.

A bewildered Redknapp, who heard about the speculation as he was preparing his team to face Bolton at the Reebok stadium tomorrow, said: "I'm definitely not leaving. It's absolute nonsense. Absolute rubbish. I couldn't be happier than I am here. Not a chance of that happening. I love it here. It's crazy rumours.

"Who starts these rumours? Who comes out with this sort of rubbish? Some idiots. It happens all the time in our profession. It seems when things are going well someone wants to upset it a bit."

Part of the speculation suggested Redknapp was contemplating a return to cash-strapped Portsmouth for the third time if new investment was forthcoming, but the Spurs boss was equally dismissive of such talk.

Redknapp said: "Someone said the other day that I'd got a group of investors to buy Portsmouth. That's the type of rumour that happens. Absolute rubbish.

"I do leave. I just walk off and go. That's how I am. I walk in one day and I'll go 'I've had enough I'm going home.'

"I am a bit like that if I'm upset about something. But I've no intention of doing that here. I couldn't be happier.

"I get on very well with the chairman. I have created a great atmosphere at this football club. People walk around here with a smile on their face, maybe more than they have ever done."

The Spurs boss, however, did spare a thought for his old club and in particular Portsmouth manager Paul Hart.

He continued: "It's been a difficult year for them. They've sold £80million worth of players and it's sad to see them in that situation.

"I just hope the guy (new owner Sulaiman Al Fahim) sticks to his word and gives Peter Storrie (chief executive)the help he needs to sort the club out.

"It's difficult for Harty. I took him there. It's just sad. As somebody said they've (Portsmouth) found the only Arab who seems to be struggling for money."

Redknapp, however, defended his own record at Fratton Park which saw a host of big name players win the FA Cup at Wembley less that 18 months ago.

Redknapp said: "People say 'You bought players like (Lassana) Diarra.' Yeah, well they (Portsmouth) paid £5million for Diarra and paid him £50,000-a-week. But he was there for less than a year and they sold him for £22million. Where is that money? Where is the money for Glen Johnson. Where does it all go?"

Redknapp admitted he realised there were problems at Portsmouth under former owner Sasha Gaydamak but he urged Hart to keep believing the club's problems could be surmounted.

"You've got to keep going," said Redknapp. "I sensed with the previous owner things were not right. You need owners who are interested in the football club. Who want to support the team.

"I don't know why people get involved in football clubs when they are not really that interested in the club. That is what has happened to Portsmouth.

"When they got £5million compensation for me they were really happy to accept the money. In fact, I think they called a taxi for me."

William Hill spokesman Graham Sharpe explained the odds tumbling, saying: "It is probably a bandwagon effect as usual, based on unsubstantiated gossip, but in volatile markets of this nature you can't afford to take a chance and we are being inundated with calls from punters wanting to bet that Harry will be the first to go."

Meanwhile, Tottenham striker Jermain Defoe was back in full training and could start against Bolton with a protective dressing on the two fingers he dislocated against Burnley.
