Hansi Flick was happy to see his Barcelona team take all three points against Espanyol in the derby on Sunday but wants more from his side going forward.
Barcelona roared into a 3-0 lead but then fizzled out in the second half and conceded when Javi Puado grabbed a goal back for the visitors.
Flick says his team lost concentration and wants them to improve for their midweek Champions League clash.
“A derby is always difficult. We showed a good level in the first half, but in general we didn’t play as we usually do,” he told reporters.
