The two sides go head-to-head in Berlin, with both aiming to complete a treble.
Four-time Ballon d’Or winner Messi says Barcelona “want to win it all”, but knows that Juventus have superstars in their own right that could make Barca’s task very difficult.
"It's a Champions League final, so we have to go through a lot because we know it is not easy to become champions again,” Messi told Times of India.
“Our dream is to win it all. We know that we will face a very tricky opponent Juventus are very strong, a big team. It is a final and anything can happen, but we will prepare and approach it as we have approached other finals before.
“Juventus like us have had a great season winning the league and cup in Italy. Moreover, they have reached the final by beating a strong Real Madrid team.
“They have some great players like Carlos Tevez, Andrea Pirlo and Paul Pogba. Defensively they will be a tough team to crack.”
