Barcelona president Josep Maria Bartomeu was pleased with the manner of victory over Atletico Madrid.
After a difficult week, Barca produced their best performance of the season on Sunday.
"I focus on the football. Changes have been made outside of that, but the good part has been what we have seen on the field. The La Liga season is very long and there is still the second half to go.
"We are all more relaxed. When the team are doing well and the supporters cheer them on like today, we are all more relaxed."
