Robert Lewandowski scored his first Barcelona hat-trick as the Blaugrana met expectations with a dominant 5-1 win over Viktoria Plzen to open their Champions League campaign.
Barca’s three first-half goals were more than they managed over the whole group stage last season (two) when they were dumped into the Europa League, though sterner challenges await.
Plzen had moments against an unconvincing Barca defence, with Jan Sykora netting just before the break, but the hosts were already ahead thanks to Franck Kessie and Lewandowski, who made it 3-1 on the stroke of half-time.
Although the tempo slowed slightly, Barca remained dominant after the break and Lewandowski ensured he became the first player to net a Champions League hat-trick with three different teams before Ferran Torres got in on the act.
Barca deservedly went in front early when Jules Kounde’s header from a corner set up Kessie to nod in on his first start for the club.
Plzen looked set to level when Andreas Christensen clumsily tripped Jhon Mosquera in the box, but a foul on the Dane was spotted following a VAR review.
That reprieve was added to soon after as Lewandowski ruthlessly found the bottom-right corner from 20 yards.
Plzen at least appeared to be going into the break within touching distance thanks to Sykora converting from close range, but the excellent Ousmane Dembele teed up a stooping Lewandowski header to swiftly restore the two-goal lead.
Ansu Fati surprisingly sliced well wide in the first minute of a second half that was significantly less intense, but his wastefulness mattered little.
Lewandowski increased the deficit and cap his hat-trick with another sumptuous 20-yard finish after a neat interchange with Torres.
The Spain winger then rounded things off with a thumping strike from Dembele’s cross.
