Goals from Griezmann and Arthur led Ernesto Valverde's side to a much needed win, easing the pressure on the Barca coach after a below-par start to the season.
Barcelona forward Antoine Griezmann is convinced his side's all-round display will get better as the season unfolds.
Goals from Griezmann and Arthur ensured Barca secured a much-needed 2-1 LaLiga victory over Villarreal on Tuesday night following their shock loss to Granada on Saturday.
The win eases the pressure on the Barca boss Ernesto Valverde and France international Griezmann who broke the deadlock at the Camp Nou, believes they will hit their best form very soon.
"We are far from our best version," Griezmann said as Marca quoted. "But with the matches to come everything will be better.
"You have to keep working. There are new players that have just arrived. We try to do our best in the group, in the field."
Griezmann also confirmed much is expected from his current club compared to his former side Atletico Madrid.
"It's not Atletico, it's different," he added. "I'm not too bad, right? Three goals so far. I can do better, yes. But I have to keep working."
