Eriksson insists he has not been in contact with Chelsea

The Swede has repeatedly been linked with the job since Roman Abramovich took control of the club last year.

And Eriksson said a poor Euro 2004 for England and failure for Claudio Ranieri at Chelsea could see him change roles.

"I have a contract but of course much relies on what happens in the spring and summer," Eriksson reportedly told Swedish journalists.

"Let's say England lose every game 3-0 in Portugal then I suppose I will get the sack before we get back.

"If that happens and if, let's say, Chelsea has been a flop from now until May, then something can happen."

Eriksson stressed, however, that he had not been in talks with Chelsea.

Quoted in The Sun newspaper, he said: "At the moment, I don't think of any clubs in the Premiership as most have good managers.

"I also know that I can't improve the players at Manchester United, Arsenal or Chelsea as they have good managers and coaches.

"I don't want to be a loser and that is why I must be very careful the next time I choose a club or a country.

"I must join a club where I can improve thngs. The absolute best club would be a 'sleeping giant' with a great following, big ground and good economy.

"If I take a club in England, it must be a challenge. I want to be a winner."

Eriksson added: "Until we fly home from Portugal, I will be giving everything for the England national team."

Ranieri has admitted he will not be surprised if he loses his job following the arrival of new chief executive Peter Kenyon.

The Italian has been warned by Kenyon that it would be a "failure" if the club does not win anything this season.

But Ranieri revealed: "I could be sacked even if I win something.

"When the owner or chief executive changes at a club, it's normal to change the manager also - it is unusual if he stays."

Ranieri believes upcoming matches against Premiership leaders Arsenal in the league and FA Cup fifth round could seal his fate.

He said: "This month is very important. The two matches against Arsenal could change the season.

"We want to win something. It is our ambition and we will try, but I could still go.

"If I'm the man who wins things, that will be my pleasure. If not, it will be the pleasure of the next manager."
