Harry Redknapp's future as Tottenham Hotspur manager is shrouded in uncertainty after it emerged that he is in conflict with the chairman, Daniel Levy, over a new contract.

Redknapp has no intention of resigning but could be sacked by Levy, who is furious at the manner in which the club missed out on Champions League qualification. Tottenham had a 10-point cushion in February and the chairman holds his manager responsible for the failure. The pair are due to hold talks imminently.

Levy suspected Redknapp's protracted link to the then vacant England manager's job led him to take his eye off the ball. The relationship between the pair has been spiky for some time, with each having the capacity to rub one another up the wrong way, and Levy is unwilling to meet Redknapp's demand for a lengthy new contract to replace his existing deal, which has 12 months to run.

Leading figures within the Premier League managerial fraternity say that it would not surprise them were Redknapp to part company with Tottenham. David Moyes, the Everton manager, would be the strong candidate to take over in the event of a vacancy. Moyes, too, has 12 months remaining on his contract and, despite holding several meetings with the Bill Kenwright, the Everton chairman, since the end of the domestic season, he has yet to sign a new deal.Brendan Rodgers, the new Liverpool manager, had his admirers at White Hart Lane, after impressing last season at Swansea City but his move to Anfield has taken him off the market.

Redknapp has had only informal arrangements with a personal agent in the past but he appointed Paul Stretford, who represents Wayne Rooney, among others, to conduct the negotiations with Levy over fresh terms. Levy was surprised to learn that Redknapp, 65, wanted three further years.

There has been public manoeuvring from Redknapp. He said last Tuesday that Levy ought to hurry up and offer him a new contract because the uncertainty could infiltrate the dressing-room if he were to enter the new season without an extension.

"It's not a case of me looking for security," Redknapp said. "What it's about is players knowing you've only got a year left on your contract and knowing that it doesn't work, basically. I think it's a situation of 'Well, he might not be here next year'. You don't let players run into the last year of their contract if you think they're any good and you don't let managers run into the last year of their contract if you think they're any good."

This appeared to fly in the face of Redknapp's contention that the talk linking him to the England job had zero effect on Tottenham's players and was not a cause for uncertainty. His comments went down very badly with Levy and it is clear Redknapp's position was not strong enough for him to make such suggestions. His timing was also unfortunate, coming in the wake of Levy suffering a bereavement.

There is no question, though, of Redknapp quitting. He spoke out after rumours circulated on Twitter that he had tendered his resignation. "I haven't resigned and I have no idea why it is being suggested that I have resigned," he told ESPN. "This is an outrage. It's an absolute liberty for people to be putting around this kind of rumour on the internet. It is not true. There is not a chance I will resign. Why should I? I have a year left on my contract."
