It's difficult to play without barca fans, Vidal admit ahead of Barcelona vs Bilbao game to be played in a "strange" atmosphere behind-closed-doors, insisting it is "difficult to concentrate" without Barcelona fans being present to cheer the team on.
2019-20 La Liga campaign was suspended in March due to the coronavirus outbreak, along with every other major league in the world.
Football is back but clubs are now having to adapt to a new competitive style to play in empty stadiums, and Vidal admits that his motivation to even "want to go on the pitch" has been in short supply since the restart.
"It's strange and complicated, from the things we have to do before games to the fixed protocols, as they are things you couldn't imagine before," the Barca midfielder told Radio Cooperativa.
"People gave you feelings we don't have now before we even got to the stadium. Now the atmosphere has changed completely.
"You don't have the motivation of your fans and it's very difficult to concentrate or, even, to want to go on the pitch.
"Football is about the atmosphere its fans create."Vidal said
Barca got straight back to winning ways by seeing off Mallorca and Levante in comfortable fashion, but relinquished top spot in La Liga after being held to a 0-0 draw by Sevilla on Friday.
Athletic Bilbao are next up for Barcelona on Tuesday night, and Vidal admit the fact that the Spanish champions have a difficult game to keep pace with Real Madrid who are top of the table.
"It will be a very intense and very hard game and we have to improve because Athletic are very complicated," Vidal explained.
"We have to recover as soon as possible between matchdays." Vidal added
Meanwhile, Barcelona still have champions league to fight for and will first have to battle Napoli in a round of 16 second-leg tie before 2019/2020 champions league becomes a straight knockout affair, with all remaining fixtures set to be played in Lisbon.
The Chilean international added, "If we beat Napoli, it'll be one-legged games and I like that because you're playing for it all in 90 minutes.
"In those circumstances is when important players have to show up, I want to do that."
