And Redknapp has himself rubbished talk that he is facing the sack, insisting he is ready to extend his current contract before it expires at the end of the season.
"I'll sign maybe today or tomorrow," he told reporters.
"Tony has offered me an extension for the next two years. I'll sign it. I haven't read it, I probably won't even read it, I will just sign it.
"If they put it in front of me today I'll sign it today, if they do it next week I'll sign it next week."
When asked about reports that he could be sacked, Redknapp said: "Absolute rubbish, we've had two games.
"That is absolute rubbish. People don't understand the game and want to make nonsense."
The QPR manager also confirmed that Crystal Palace have made a bid for left-back Armand Traore, but denied his club made an offer for West Ham midfielder Mohamed Diame. New signing Eduardo Vargas is also still in Italy awaiting a work permit.
