Coutinho scored from a tight angle just three minutes after coming off the bench, latching onto a cross from his former Liverpool team-mate Luis Suarez. This is the kind of game that is hard for us.
"It's a really special moment for me because I have just arrived". Obviously it takes a little while to adapt, but I think I have settled in well.
Gabriel Paulista lost the ball to Suarez who ran clear to find Rakitic on the edge of the area and the midfielder made no mistake in firing past Jaume to seal Barca's place in the final.
The victory means that Barcelona remain on course for a treble during Valverde's first season at the Nou Camp.
Rajinikanth's Kaala takes 2.0 release date, to hit screens on April 27
A source says, "The VFX and CGI work on 2.0 is happening across at least three studios, between two continents". Last week, the speculations were rife that the filmmakers have plans to postpone the release date again.
Barcelona then had a scare as Rodrigo headed against their bar around the quarter-hour mark.
On Sunday afternoon, meanwhile, Coquelin will get his first taste of the Valencian derby, as his side host Levante at the Mestalla.
It was the sixth straight loss for Valencia in all competitions. He had still managed 49 passes, 48 of them to a team-mate, in the first half. "I normally wait to make changes, but this time I saw it clearly", he added.
After a stunning save from Jasper Cillessen to deny Valencia a lifeline through Jose Gaya, Suarez won possession from a defender and teed up Ivan Rakitic to round out the scoring.
Goncalo Guedes was unable to keep his header down from Zaza's clipped cross in the 66th minute and Vietto advanced into the box from the left seconds later to get off a shot that was comfortably dealt with by Cillessen. All of their promise in the first-half was dashed as they conceded a second goal of the night to make it 3-0 on aggregate.
