Barcelona defender Gerard Pique says they welcome a revitalsed Real Madrid this season.
Madrid are set for a change in style under Jose Mourinho and Pique is relishing the tactical battles ahead between Guardiola and the Portuguese coach.
"It will be fun. They are two coaches with different styles, even though Mourinho says he is an attacking coach," he said.
"But Guardiola has shown you don't need the character of Mourinho to become a great team."
Guardiola is likely to select several of his Spain stars on Saturday in the Supa Copa return leg against Sevilla, while some of the side's young players also look set to receive another opportunity.
"Using the youth team is always an effective solution for Barca," Pique said.
"They shouldn't be doubted (despite the defeat in Seville). They have shown they can perform well and we have to place our confidence in them."
