"I just want to win the final and end the season with another trophy".
"It has been a spectacular year in which we have won the league and we are in the final of the Copa del Rey".
Lionel Messi also threw his weight behind their manager Ernesto Valverde, saying the tactician "he was practically blameless for what happened with Liverpool".
Barca's all-time top scorer became club captain for the first time this season but, despite the Catalans retaining the Liga title with three games to spare, Messi can not shake off the bad memories of the loss to Liverpool.
Messi's first act was to tell supporters of his determination to win the Champions League for the first time since 2015, saying he would "do everything to bring that attractive and desired trophy back here to the Nou Camp". There must be questions asked about how little the team managed to create going forward, how Messi was offered no support by Philippe Coutinho and Sergi Roberto.
Messi insisted: "I sincerely believe that he has done an impressive job during his time here so far and he was not responsible for the elimination in Liverpool".
Messi replied: "I never had any doubts, I am stil keen to be here regardless of the disappointment". "Last season we did the double and this season we can do it again".
Barcelona is seeking a fifth straight Copa del Rey title and its record 31st of all time, but it will have to do so without the injured likes of Luis Suarez and Marc-Andre ter Stegen.
Due to their injury problems and the unpredictable nature of finals, Valencia head coach Marcelino Garcia Toral is in optimistic mood against a side that won the league title by 11 points. "We are all disappointed and very much, but it's not my turn to say [whether or not there will be changes]". "That's why I think we were all in our heads in the Champions League and that's why the disappointment was so great, repeating what happened in Rome. If we don't go out with the right attitude we could suffer", he said.
In the 2017/18 season, Roma lost 4-1 at the Camp Nou before a surprise 3-0 win at the Stadio Olimpico saw them through.
"They quickly scored a goal, we lowered our heads thinking that it could happen again. The capacity of Barca in attack is huge and will force us to be nearly flawless in defence over the 90 minutes".
