Girona head coach Michel was left to rue a lack of attacking options but urged his side to cope with injury absences after Saturday's 1-0 defeat to Real Sociedad.
Last season's surprise package Girona have struggled to find form this campaign, slipping to 13th in the LaLiga standings after their fourth defeat in 10 games.
Mikel Oyarzabal scored the only goal of the game on the stroke of half-time as Girona put in another disappointing performance at home.
Michel lamented his side's depleted attack following injuries to forwards Bryan Gil, Yaser Asprilla and Abel Ruiz.
"We have to keep working, the offensive potential of the team without injured players... you lack depth, you always lose somewhere, we don't have any player on the pitch who can play as a winger," the Spanish manager told reporters.
"We need to improve in our final pass, in our one-on-one determination, to get into the box more. These things are the most difficult thing in football, scoring goals.
"Last year we had a lot of goals, this year it's harder for us."
Fans at Girona's Montilivi stadium expressed their frustration after another underwhelming performance, but Michel backed his players in the face of criticism.
"Fans have to understand the process in which the players are. There is no player, because I would not allow it, that does not give his maximum performance in terms of attitude, mentality, illusion, motivation, energy," he said.
"If they say that we play good or not, I respect that, but we try to play good football and mistakes are part of the game.
"It's not easy, we faced a team with 14 internationals and for the first half hour we tried to go for them... you can't say to any Girona player that they don't give their all for this shirt."
Girona will look to bounce back when they Slovan Bratislava in the Champions League on Tuesday.
