Arsenal vice-chairman David Dein has told Chelsea that Patrick Vieira and Thierry Henry are not for sale - no matter how much they offer.
Striker Henry is reportedly a £50 million target for the big-spending Blues after Russian billionaire Roman Abramovich's takeover.
And Arsenal captain Vieira, who only has one year left on his current deal, has been linked with a £25 million move to Stamford Bridge.
But Dein insisted Chelsea's new-found wealth would make no difference to the Gunners' stance, and promised fans both players would be at Highbury next season.
He told Sky Sports News: "All the speculation is very annoying. Thierry Henry and Patrick Vieira will not be leaving Arsenal Football Club - the players have said it and the club has said it.
"We will not be selling our best players, it's as simple as that. We will not be weakening our squad to strengthen the opposition.
"The money is not the issue. They will both be with us next season and hopefully for many to come. We're working on it - we're on the case."
Dein calmed fears over apparent delays in Vieira signing a new contract at Highbury.
The Frenchman will be out of contract at the end of this season but Dein was relaxed about negotiations.
He added: "The timing's his and we're not going to force the issue. He knows when he is ready to sign, the offer is on the table for him.
"He said the other day he will sign. He will be with us for sure next season and hopefully for many seasons to come."
