Lionel Messi missed a penalty kick but rebounded by scoring his record 350th goal in the Spanish league in Barcelona's 2-0 win at Alaves on Saturday.
Messi also scored the second in leading the club to its second consecutive victory to start the league.
Barcelona was still without Ousmane Dembele, who was announced as Neymar's replacement on Friday, and it also couldn’t count on the injured Luis Suarez.
With Messi as its lone star, Barcelona struggled in the beginning at Mendizorroza Stadium, but it gradually took control and cruised to victory following Messi's pair of goals in the second half.
Messi missed the penalty when his mid-height shot into the left corner was saved by the fingertips of Alaves goalkeeper Fernando Pacheco.
Alaves, who surprised last season as a promoted club by finishing ninth in the league and reaching the Copa del Rey final against Barcelona, opened with a 1-0 loss at Leganes.
Brazil midfielder Paulinho, signed by Barcelona for $47.2 million (40 million euros) in the offseason, came into the match as a substitute late in the second half to make his club debut.
