Alba insists he remains fully focused on his football and will not allow himself to be drawn into the debate.
"I cannot say anything as I am focused on playing well for Valencia," he said.
"My representatives are there to handle everything that happens at a higher level. I am not thinking about these things because I do not know if they are true or not.
"I am very happy here and I only think about maintaining and then improving. Anything else is for my representatives to deal with."
