Miralem Pjanic is happy with his first week working under Barcelona coach Ronald Koeman.

The former Juventus midfielder says the players are adjusting quickly to Koeman's system.

He said, "We have good feelings. We work a lot. We try to adapt to his ideas and apply them on the field.

"We are working very hard, which seems to have changed a lot compared to last year. The workouts are difficult. We must now prove it on the field, in the first match.

"Starting with a win would give us a lot of confidence."
