Barcelona - Barca boss Luis Enrique is a former teammate and friend of Guardiola's from their time together at the Camp Nou and he believes the attacking intent of both sides will lead to a great spectacle.
"There is only one ball and we both want it. Tomorrow we will see who is better, but it will be one of the most attractive games you can see in European football.
"Knowing Pep, I am sure that there will be things that will make like difficult for us, but during the season we have overcome the problems the opponents have put in front of us. Against Bayern we will try to do the same."

Bayern travel to Catalonia without the injured Arjen Robben, Franck Ribery, Holger Badstuber and David Alaba, whilst Robert Lewandowski will have to wear a protective mask after breaking his nose and cheekbone in last week's German Cup exit on penalties to Borussia Dortmund.
However, Enrique dismissed suggestions his side's clean bill of health made them clear favourites to progress to next month's final in Berlin.
"I don't think there is a favourite in a semi-final of this level.
"Independent of who we are playing, we always try to play our game because we don't know how to play in a different way. At home, with our fans, we will be stronger, but in the second game we will prepare in the same way."
