Coutinho off the mark but Barca held by Sevilla
Barca and Sevilla each have seven points after three games and are fifth and sixth in the standings, with champions Real Madrid top on 10.
Philippe Coutinho scored his first league goal since returning to Barcelona to help his side draw 1-1 at home to an excellent Sevilla side in La Liga on Sunday as the Catalans dropped points for the first time under Ronald Koeman.
Europa League holders Sevilla took an early lead when Dutch forward Luuk de Jong pounced on a poor headed clearance in the area and smashed into the net, flummoxing Barca keeper Neto.
But the Catalans hit back less than two minutes later when club record signing Coutinho, back at the club after spending last year on loan with Bayern Munich, reacted fastest to fire home after a Lionel Messi pass was deflected into his path.
Antoine Griezmann missed a good chance to give Barca the lead before halftime but hit the side netting while midfielder Frenkie de Jong should have scored late in the second half but missed the target from inside the area.
Sevilla could also have snatched a winner, with Youssef En-Nesyri seeing a deflected shot hit the crossbar before failing to test Neto with a free header.
