Lionel Messi returned without a beard and with a goal and two assists as Barcelona resumed their La Liga title challenge on Saturday with a thumping 4-0 victory over Real Mallorca.
After three months away because of the coronavirus pandemic, Barça exploded into the lead with just 64 seconds played when Arturo Vidal headed in and Martin Braithwaite struck a second from a Messi headed assist.
Jordí Alba latched onto a Messi pass to add a third but not before play was briefly stopped by a pitch invader, who was able to run on, despite the match being closed to fans.
Messi then scored a fourth in injury time for his 25th goal of the season.
His goal was set up by Luis Suarez and the sight of the Uruguayan coming off the bench would have been welcome for coach Setién too.
Suárez has not played since undergoing knee surgery in January and was able to recover during the suspension. He could play an important part in the run-in.
Asked what pleased him most, Setién said: "The satisfaction of seeing Luis again on the field. You have to admire the performance he gave in those 35 minutes that he played. Starting like this is very important for him and for the team as well."
Barcelona were in front after just over a minute as Frenkie de Jong did well to recover the ball from a loose touch before Alba sent a deep cross to the arriving Vidal, who headed in.
Mallorca were under relentless pressure as Braithwaite and Messi both went close to adding a second. Mallorca's Takefusa Kubo, on loan from Real Madrid, forced a good save out of Marc-Andre ter Stegen on the break.
But Barca scored a second before half-time as an Alba cross span up and both De Jong and then Messi feathered headers across for Braithwaite to bang in on the half-volley, his first goal for the club.
Both teams eased off in the second period and there were smiles on the Barcelona players' faces when a pitch invader ran on in the 52nd minute wearing an Argentina shirt. He posed for a picture with Alba before being escorted away.
Alba added a third after finishing off Messi's clipped ball over the top and then Messi grabbed a goal himself. Suárez fooled his marker by letting the ball run across his body and Messi weaved inside where he could unleash with his right foot.
Mallorca's defeat, combined with losses for Leganes and Celta Vigo, made it the perfect day for Espanyol, who made up ground on their relegation rivals by beating Alaves.
