"We have the opportunity to put that little disappointment behind us", Valverde said at a press conference on the eve of the game, which will be played at Atletico Madrid's Wanda Metropolitano stadium. La Liga is a lot of games, and everyone wants to win the Copa.
Messi hit Barca's second with a powerful finish after some a fine run and lovely cutback from Jordi Alba, their association a real feature of Barcelona's play this season.
And things got worse for them early in the second half.
With much talk recently about how Barcelona need to evolve into the future, this Copa victory was all about their "old guard" of 30-somethings - as Suarez scored twice, Messi helped himself to another all-time record and Iniesta reminded us of what he still can do. In their draw against Barca, they shipped two goals in the 87th and 89th minutes.
So, while missing out on the Champions League and the collapse in Rome will still hurt for the players and also the fans, Saturday was a return to happy times for Barcelona as the Catalans claimed their fourth Copa in a row to complete the first part of what should be a fine finale to this season.
Messi and two-goal Luis Suarez led the way, with the Argentina star scoring and claiming two assists.

The rookie standout continued his splurge in the fourth quarter and made a floater to give the Jazz an 81-80 edge with 9:50 left. We threw the first punch, they punched us back tonight and now we have to go on the road and get a win at their place.
With that, Messi became the second player in Copa del Rey history to score in five different finals (with six goals in total).
"We began the first half very well", Suarez said.
The matchday's other big game takes place at the other end of the table when Udinese host Crotone on Sunday in a contest whose outcome could have massive ramifications when it comes to which three teams will be relegated by the end of the season. Under the Italian coach, Sevilla was eliminated by Bayern Munich in the Champions League quarterfinals and dropped to seventh place in the Spanish league, outside the qualification zone for the Europa League.
Another surprise loss this weekend would certainly settle the argument, even if it seems odd to declare a team under pressure six days after they marked the longest unbeaten run in La Liga history.
The King's Cup would certainly have been third on Barcelona's list of priorities only a month ago, but the shattering Champions League defeat by Roma has altered perceptions of what might have otherwise been a stellar campaign.
