Moscow: Barcelona eased into the Champions League last 16 after record-chasing Lionel Messi fired a first-half double as the favourites rediscovered their European verve to overcome Spartak Moscow 3-0 on Tuesday.
Barcelona fullback Daniel Alves opened the scoring in the 16th minute and Messi added two more in the space of 12 minutes before halftime with his 79th and 80th goals during this calendar year.
The Spanish club, who now have 12 points from five games after shrugging off the 2-1 defeat at Celtic this month, controlled the tempo with their famous tiki-taka passing game on Moscow's slick artificial turf and often picked holes in Spartak's porous defence.
The defeat eliminated the Russians, who had only a slim chance of advancing from Group G before Tuesday's match. Their only hope now is finishing third and earning a Europa League berth depending on the result of Benfica's match against Celtic later on Tuesday.
"We couldn't allow what happened at Celtic to happen again," Messi said.
"We knew we had to come out strongly right from the start because it's always tough to play away in this competition and even more so given the state of the pitch.
"Obviously the fact we didn't concede is a boost for everyone, especially when we have been letting in too many goals recently."
Brazil international Alves beat Spartak goalkeeper Andriy Dykan with a low blast from outside the box after the Russians failed to clear the ball following Barcelona's build-up near the goal.
Messi doubled the lead 11 minutes later, firing into an unguarded goal with his right foot after Dykan did well to stop the initial shot by Andres Iniesta.
The Argentine wizard made it 3-0 after rounding Dykan and rolling the ball into an empty net with his left foot following a great through pass by Pedro.
While Alves scored his first goal this season, Messi is closing in on a record with 80 in 2012.
