Mallorca came back from going two goals down to run out winners on the night, but not before Arango and his teammates were booed relentlessly by fans.
"If they boo you the truth is you feel bad," said the Venezuela international. "I honestly do not know if these fans are for or against the team. I cannot answer that.
"The fans sometimes do not understand. They booed us at 0-2 and then by the end they were signing 'ole, ole'. But for five minutes they constantly booed and whistled instead of supporting us."
