Redknapp is set to rest some of his senior players in the quarter-final at Watford but has resisted the temptation to raid his youth team and plans to take an experienced squad to Vicarage Road.
Redknapp said: "Arsenal have so many 19 and 20-year-olds who are fantastic, they can play them.
"How many more teams can afford to do that? None."
The Carling Cup holders will reach the semi-finals for the third successive year if they win but Redknapp said: "League points are the most important thing to us with the position we are in. It has got to be that way."
