The La Liga leaders will wear the updated replica of their strip from 20 years ago, which was originally worn by the likes of Rivaldo, Luis Figo and Pep Guardiola, during Saturday's crunch fixture with arch-rivals Real Madrid at the Santiago Bernabeu. The Copa del Rey win was Barcelona's fourth in six games at the Bernabeu and in each of those they have scored three or more.
Madrid had the better of the first half and should really have been ahead, but Luis Suarez opened the scoring soon after the break, and a Raphael Varane own-goal and Suarez penalty saw the Catalans through 4-1 on aggregate to a record sixth successive Copa final.
Isco is back in the Real Madrid squad for Saturday's Clasico clash with Barcelona after nearly a month on the sidelines with back and neck pain.
The second goal came less than 10 minutes later, when Varane tried to intercept Dembele's cross for Suarez and ended up finding his own net.
Bale is continuing to struggle with life at Real Madrid, with club manager Santiago Solari preferring to have him on the bench than in the starting line-up.
"We have to get back on our feet quickly and not lose perspective", said Solari. But they took the ones they had.
"It was a game of two halves", Valverde said in a news conference.
R. Kelly Went From Jail to McDonalds
The artist was escorted to a black van by his lawyer Steve Greenberg , and did not answer any of the media's questions. Kelly posted bail Monday evening after spending the weekend in jail in Chicago on multiple charges of sexual abuse .
Los Blancos held a slight advantage, having scored an away goal in a 1-1 draw at the Camp Nou in the first leg.
At one point in the Pep Guardiola and Jose Mourinho era it felt like the teams played each other every week but things have calmed down a bit since then.
Kevin-Prince Boateng is the only notable absentee from the Barcelona squad named by Valverde for Saturday's trip to the capital.
It is in defence where doubts remain.
Despite winning four Champions League title with Madrid, Bale has endured a mixed time at the Bernabeu and is being linked with a departure ahead of the summer transfer window.
There is still time to tighten up and Samuel Umtiti's return to fitness will be a welcome boost if he can find sharpness before the end of the season. They must only hope they do not have to meet Barcelona over two legs in the Champions League.
"Oddly, in Lyon, we had 25 shots with this same team, we didn't score and there was talk of a crisis!" he said. "There are important matches to come".
