Barcelona coach Ernesto Valverde knows they go into their clash with Real Betis carrying extra responsibility.

The match will be played in the immediate aftermath of terrorist attacks in Barcelona and Cambrils, clearly something on the minds of the club staff.

"The best way is to keep going but as things are in this world, we are all potential victims.

"You go to a subway station, a football stadium..."
