Lionel Messi showed exactly why he was given a lucrative contract as his 650th Barcelona goal helped Ronald Koeman's side to a slender 2-1 win over Athletic Bilbao.
A report by El Mundo claimed the deal Messi signed at Camp Nou in 2017, which expires at the end of this season, is worth more than €555 million (A$883 million).
He demonstrated his value to this Barca team midway through the first half on Monday (AEDT) with his 49th successful free-kick strike for the Catalan giants.
Jordi Alba put through his own net early in the second half to draw Athletic level, but Antoine Griezmann ensured Barca leapfrogged Sevilla and Real Madrid into second - 10 points behind leaders Atletico Madrid - with a close-range finish 16 minutes from time.
Unai Simon twice denied Barca inside the opening seven minutes, first pawing away Messi’s clipped effort from close range before diverting Griezmann’s powerful drive over the crossbar.
There was little the Athletic goalkeeper could do to deny Messi after 20 minutes, the Argentinian whipping a sumptuous free-kick into the top-right corner from 25 yards.
Ronald Araujo fizzed an effort wide soon after, while Ousmane Dembele lashed over from a promising position shortly before the interval as Barca dominated.
Athletic drew level four minutes after the interval, however, as Alba turned Raul Garcia's left-wing cross into his own net under pressure from Oscar De Marcos at the back post.
Simon superbly kept out Miralem Pjanic's header shortly before the hour mark, while Griezmann nodded wide from Dembele's teasing cross.
The France international had the final say, though, sliding home Oscar Mingueza's low cross into the roof of Simon's net to seal a fourth consecutive win in all competitions for Barca.
