Gerard Pique insists he has a "phenomenal" relationship with Sergio Ramos despite reports of a rift within the pair.
The Barcelona centre-back has been the subject of jeers from Spain fans during national team training sessions in recent days in the wake of his support for the Catalan independence referendum last Sunday.
Pique held a news conference on Wednesday where he insisted he is fully committed to the national team's cause and would not be forced into retirement by his critics.
"It's a lie that I get on badly with him," he said. "We will be partners in a business I proposed.
"My relationship with him is phenomenal. I'd like you to see that."
"It's the million-dollar question and I'm not going to answer it," he said when asked if he supported a split. "Footballers are global figures and I can't put myself on one side or the other. I'd lose half of my followers from Catalonia or Spain.
"My sons, for example, are Colombian, Lebanese, Catalan and Spanish. We're a global world."
He continued: "The relationship between Spain and Catalonia is like a father and an 18-year-old son who wants to leave home.
"Spain has two options: to talk like a father should, or to see the son leave. It's difficult to understand what's happening in Catalonia without being there.
"What does it matter what I think? What matters is that politicians do their job and find a solution."
