Manchester City will hope to carry momentum from their stunning victory over Real Madrid into Sunday's Carabao Cup final.
City are bidding to win the EFL Cup for a third year in succession and a fifth time in seven seasons as they face Aston Villa at Wembley.
They go into the game in good spirits after defying the odds to come from behind and beat Spanish giants Real in the Champions League on Wednesday.
He said: "The result of the last days is past, it is gone, and now we focus on the final, a different competition.
"They are a historic team, they have a Champions League (European Cup win) in their history and I think it will be a fantastic game.
"They are well organised and have a keeper with incredible experience in Pepe Reina. They have fast players up front and physicality in the middle, especially with the central defenders, good headers."
City won 6-1 at Villa Park last month but Guardiola insists that counts for little.
He said: "It was a good game when we went there but it's not good preparation for the final. We will prepare tactically and mentally knowing we have an incredible challenge to win."
