Mallorca have appealed against the decision by UEFA to suspend them from the Europa Cup.
The Spanish side were dismissed from the competition last week after the club's financial irregularities were exposed.
Mallorca’s place in the tournament looked set to be taken up by Villarreal following a UEFA Control and Disciplinary hearing last week.
Former coach Gregorio Manzano led the team to a 5th placed finish in La Liga last season, which therefore entitled them to Europa League qualification.
However, UEFA has since ruled that because of the Spanish side’s huge debts they were not liable to play in European competition.
In addition to the official appeal, Mallorca have issued a strong statement about its intent to fight, and defeat, the ban — which threatens to deprive "the club of a series of revenue in different concepts such as ticketing, sponsorship and income from the competition."
"Ethically and legally, RCD Mallorca believes reason is on their side and [the club] will not relent in the effort to show that he has earned the right to challenge the Europa League," a statement on the club's official website read.
"No one can rob these guys of what they conquered. A team that was placed 38 days in Europe, some players who fought dramatically throughout the league that won the European competition qualidication endless overcoming difficulties, do not deserve UEFA action."
New manager Michael Laudrup, who replaced the departed Manzano in the off-season, had previously admitted his hope that UEFA president Michel Platini will reinstate the Islanders back into the competition.
“I’m optimistic — I know Platini and I know he’s fair," Laudrup said.
“The committee (of control and discipline) took the decision, but we’ll see what happens. There has been no final word.”
The date for the appeal hearing has yet to be confirmed.
