Barcelona assistant Jorge Pautasso has admitted that the Spanish champions must "continue to improve" following Sunday's 4-1 win over Almeria.
The Catalan outfit laboured to the three points against the La Liga strugglers, who kept the score down to 2-1 until the final 10 minutes at the Camp Nou.
"In the second half Almeria didn't risk anything. We waited and that led us to a sense of frustration," Pautasso told reporters.
"We know we have the default strategy but our rivals don't risk anything and wait for us to make a move. We know we must continue to improve our defensive strategy. The first half was excellent."
Pautasso took charge of Barca on Sunday due to Gerardo Martino's recent suspension.
