Barcelona didn't get the result they wanted in the first leg of their Copa del Rey tie against Celta Vigo, and they'll need to be much better in the second leg if they want to advance to the quarterfinal round.
With the last-16 clash poised at 1-1 from the first leg in Vigo, Ernesto Valverde wheeled out all his big guns at the Nou Camp.
Lionel Messi was the star of the show, as he struck twice within the first 15 minutes of the game.
Barcelona: Jasper Cillessen 5 (out of 10), Nelson Semedo 6, Gerard Pique 6, Javier Mascherano 6, Jordi Alba 7, Ivan Rakitic 6, Sergi Busquets 7, Andres Iniesta 7, Andre Gomes 6, Lionel Messi 8, Luis Suarez 7.
New signing Philippe Coutinho watched from the Camp Nou stands following his club-record transfer from Liverpool earlier this week.
"Messi is the best player in history and the best in the world by a difference", Alba told reporters after the game.

A tsunami advisory signals a threat to those in or near water, as strong currents and waves could be risky . Hazardous waves, between 0.3 meters and 1 meter above tide level, are forecast to hit Honduras and Belize.
"I think we have a great connection". Barcelona's all-time scoring leader swept Alba's cross past Sergio Alvarez despite the goalkeeper getting a hand to the ball, and he followed up by firing home after another exchange of passes with Alba.
The 30-year-old forward re-signed a contract which would keep him at Barcelona till 2021 as Messi took his goal tally to 21 in all competitions.
Suarez joined the party even before the half time whistle and capitalising on Pione Sisto's sloppy back pass, Suarez found the net for the fifth game running.
"They look for each other and are happy to do so, because it is not just Alba assisting Messi".
Also in the last eight of the Copa del Rey are Real Madrid, Atletico Madrid, Valencia, Leganes, Alaves, Espanyol and Sevilla.
