Real Madrid are against staging a clash between the Catalans and their Basque rivals at their home ground because of the alleged anti-Spanish feeling among some of their fans
Real Madrid are against staging the tournament decider at their ground because of the alleged anti-Spanish feeling among certain sections of the Barcelona and Bilbao support.
Indeed, the last time the two sides met in the Copa del Rey final, at Mestalla in 2009, some fans from both clubs booed the Spanish national anthem.
The Spanish Football Federation (RFEF) has yet to make a final ruling on the venue but Alves is of the opinion that the showpiece event would not go ahead in Madrid - even if Bilbao were not Barca's opponents.
"We know that, in terms of capacity, the Bernabeu puts itself forward [as the ideal venue]," the Brazilian told reporters at a press conference in Leverkusen on Tuesday evening.
"But I believe that Barcelona will never be allowed to play a final at the Bernabeu."
Alves insists that he does not mind where the final ends up being held but added: "We just do not want it to be on Athletic's pitch [at San Mames]."
Meanwhile, Barcelona spokesman, Toni Freixa, insists that the Catalans are baffled by Madrid's stance on the matter.
"It should be an honour for the Santiago Bernabeu and for Spanish football: the final being staged on a stage like that between two big clubs," he argued in Mundo Deportivo.
"We insists that this must be the stadium. I am optimistic as possible because we want to throw a big party for Spanish football.
"At the moment, we are in the process of proposing the Santiago Bernabeu as the final and we hope that it will be possible because it is the ideal scenario.
"We seek a field that meets the criterion of maximum capacity and equidistance between the two cities, in the interests of our fans.
"We understand that the ground which meets these criterion is the Santiago Bernabeu and that is something we have made known to Federation in conjunction with the Athletic Bilbao.
"In the coming days we can hold a meeting [with the RFEF] to nominate the venue."
Barcelona defeated Madrid to reach the final, while Bilbao saw off Mirandes in the semis.
