After scraping into the Carling Cup final against Burnley last night, Redknapp said: "That group I've got tonight is the only group I've got to go to Old Trafford with. I can't risk players because we have got Stoke on Tuesday.
"So I'll go to play United with the weakest team I can possibly find. That's how it's going to be I'm afraid.
"I've got no one else and I've got to rest people. I can't afford it, we're in a relegation battle.
"We need to get some squad players in who will come in and give me everything and be proud to play for Tottenham."
