Barcelona may have to give up its attempts to sign defender David Luiz this upcoming season.

According to ESPN, Barca defender Dani Alves thinks that Chelsea manager Jose Mourinho will do everything in his power to prevent the sale of the Brazilian defender.

"I always want the best for my friends and I tell them to come here if they can," Alves said of his Brazil national teammate Luiz. "As well as that, he is a great player. The problem is not whether he wants to come, but that in the end you have to get away from Mourinho -- and that is not going to be easy. The idea of facilitating David Luiz coming to Barca would not pass through his head, and even less if it is to strengthen us. It is more than difficult for us, almost impossible."

Mourinho recently addressed the transfer rumors and told Barcelona to look elsewhere for a defender.

"The bid? It's lost time for them," Mourinho said, according to Express. "My advice to them is to go to the second player on their list because they are wasting their time. We don't want to lose our best players. No chance."

Even Luiz has refused to address the transfer rumors.

"I will only talk about the national team because this is all I can think about when I come here, that's how I think," Luiz said, according to Fox Sports. "It was like this in Brazil during the Confederations Cup, and it will be like this here. You [press] can try everything, but you won't get anything from me."
