Ronald Koeman said Barcelona were missing a target forward as they scored just once from 20 shots on goal in a 1-0 victory over Huesca, and called for the club to sign a new striker.
Lionel Messi returned to the Barcelona side after recovering from an ankle injury and Koeman opted to play him in attack alongside Martin Braithwaite and Ousmane Dembele.
The trio attempted 15 shots between them but it was Frenkie de Jong who scored the decisive goal, volleying Messi's chipped pass into the net after 27 minutes.
