SOUNDBITE: (Italian) Massimiliano Allegri, coach of Juventus

"The team played a good first half with really good defending. We had good opportunities in our attacks but we didn't seize them. When you play a game like this you can't think you won't make mistakes. We made a mistake in the 45th minute and they scored their second goal. Messi had three shots on goal and he scored twice. In this respect we need to improve. We needed to stay in the game during the second half without trying to delay the game so we could score. That is the mistake we made during the second half."

"Barca is a team that plays football very well. They have good possession of the ball. And in charge of that are the better players who can make a difference in the balance of a game. We had a very good first half stopping (Andres) Iniesta and (Lionel) Messi. But we didn't so well during the second half."

"(about Messi being brilliant on the pitch)

"If we give him lots of space of course he will be great. If we give him less then he can't play that well. In that aspect, my team has done a great job."

"We played a great game and we feel good about it. Our rivals were tough and have players of great quality. But we concentrated and and they created few threats. We are very happy but this is just the beginning."

SOUNDBITE: (Spanish) Ernesto Valverde, coach of FC Barcelona

"The fans understood this was a game that required patience as they (Juventus) are a good team with a good defence. Sometimes it was hard for us to have clarity in their half. And at the same time they were dangerous on the counter-attack. But after the first goal we were able to find more space. So both our supporters and the team can go home happy."

"The team gains bit by bit from the feelings and the results they get. We have achieved three victories in the (Spanish) league. And for us this game was very important from many points of view, including self-belief. It will help us that this competition is very short. But it will be difficult, especially in the group stage."
