And Redknapp said: 'It's a big game, a very exciting game with two sides wanting to win. Villa are an attacking, open exciting team. James Milner's moved into midfield and doing great.
'Martin's made good signings, but we are a good team as well. I though we were excellent at Leeds and showed terrific character to win a hard tie.
'Martin understands football and has always done a good job, he knows how to put a team together and get the best out of players. He keeps it basic and gets the best out his players.
'They'll come with two wingers and attack us, they'll come to take us on. They are a good counter-attacking team because of their pace in wide positions.
'But we have good forwards, we are scoring goals, making chances, Defoe is in good goal scoring form, and I'm sure they'll be plenty of opportunities, with one defeat in 11.'
Redknapp is waiting on the fitness of Ledley King but Luka Modric and Wilson Palacios, rested for the 3-1 FA Cup win at Leeds, should return. And Aaron Lennon is closing in on a return but the game tomorrow has come too early for the England winger.
