Barcelona will appeal the yellow card issued to Andres Iniesta during Sunday's 4-2 victory over Real Betis, according to Pep Guardiola.
Spain international Iniesta was booked for diving inside the Betis area midway through the second half at Camp Nou following contact with Jefferson Montero.
Guardiola, who feels his team were denied a legitimate spot kick, confirmed after the game that Barca will attempt to have the booking rescinded.
"It's not a penalty because the referee hasn't seen it," Guardiola said.
"But we will appeal the Iniesta card."
After seeing Barca give up a two-goal lead before recovering to win the match, Guardiola dismissed any suggestions his players had been guilty of complacency.
"If there's something that this team does not do, it's ease up," he said.
"This is a consequence of not wanting to lose what one has gained over the years."
"They would have to do something very wrong for you to doubt their commitment."
While Barca are currently five points behind La Liga leaders Real Madrid, Guardiola is also of the opinion that the Catalans have had a 'very good first round' of the season, saying 'this only happens if you work hard and behave as you need to behave'.
Turning his attention to the first leg of the Copa del Rey quarter-final showdown with Real on Wednesday, Guardiola stated that Barca will try to 'play the best game possible' and will be going all out for goals because 'we know scoring away from home is much more complicated'.
Barca travel to the Santiago Bernabeu before hosting Real at Camp Nou seven days later.
