Barcelona coach Ernesto Valverde is staying calm after defeat to Levante.
That loss is Barcelona's third of the campaign in LaLiga Santander, as many as they suffered in the Spanish top flight last season.
"When you lose you always look at the coach," Valverde said in Barcelona's pre-match Champions League press conference.
"That is the case and I assume it.
"The other day Levante scored against us with their first shot.
"We controlled the game until we lost it, we were not good in attack and we have to improve."
He added: "We know what it means to lose a game. It generates a tidal wave of pressure.
"It's all right with us because it forces you to react.
"There's always a tidal wave, even when you win and you have a good all-round game."
