- Barcelona defender Gerard Pique has shown commitment to the independence of Catalan
- The star defender stated that he is ready to quit the Spanish national football team if he is deemed 'a problem'
- Pique was instrumental in Barcelona 3-0 La Liga victory over Las Palmas
Barcelona defender Gerard Pique says he is ready to stand down from Spain duty if he is deemed a "problem" by national team coach Julen Lopetegui or the Spanish Football Federation as a result of his support for the independence of Catalan.
Pique made the claim in an emotional interview following Barca's 3-0 home win over Las Palmas, which was played behind closed doors as violent scenes broke out during Catalonia's unofficial independence referendum.
According to official reports, more than 750 people were injured as security forces used rubber bullets and baton charges as they clashed with protesters.
The Barcelona defender was pictured casting his vote in the election earlier in the day played the full match against Las Palmas before speaking to reporters about the decision to go ahead with the fixture, his international future and Sunday's events in the region.
The 30-year-old told Spanish media AS: "You vote yes, no, or leave it blank, but you vote. In the Franco era, we couldn't defend our ideas.
"I am, and I feel Catalan, and I am very proud of the people, of their behaviour, like in the last seven years."
Attempts to shut down the polls by Spain's Guardia Civil led to clashes described by Catalonia president Carles Puigdemont as "unwarranted, irrational and irresponsible."
Pique, who was also critical of Prime Minister Mariano Rajoy, continued: "After what has transpired it has been my worst experience as a professional.
"It has been a tough day. There were families, children and grandparents, and the police and Guardia Civil have intervened.
He added: "The people protested without violence. I thought they would try to stop the vote in a peaceful way. Everyone has seen what happened. They've made things worse.
"This is among the worst decisions in the last 50 years. They've separated Catalonia from Spain even more and there will be consequences."
Spanish football giant Barca had asked the Spanish football authorities to postpone Sunday's game against Las Palmas, citing the unusual circumstances.

But when the club's request was rejected by the Madrid-based Liga de Futbol Profesional, Barca took the remarkable step of playing the top-flight fixture in an empty Nou Camp - winning 3-0.
Pique said: "The board tried to postpone the game at all costs, we debated it between the players and the club, and chose to play. It was difficult without the supporters.
"There were many arguments in favour and against, but we were playing for the points and the League and Las Palmas wanted to play.
The 30-year-old added "The club have decided and that's it. My opinion is not so important. I expressed mine, like the board members expressed theirs. In the end it was decided to play the game. We are a club and we are all in it together.
"But I understand perfectly those who criticise us for having played."
Pique is now due to link up with the Spanish national team for their forthcoming World Cup qualifiers against Albania and Israel but says he is willing to step aside before next year's finals if his involvement is an issue.
Gerard Pique has played almost 100 matches for Spain and helped them win the World Cup in 2010 and Euro 2012.
He said: "I honestly think I can join up with the national team because I'm convinced there are thousands of people who totally disagree with what has happened.
"I also say that if the coach (Lopetegui) or anyone from the Federation thinks that I'm a problem or a nuisance then I will step aside and leave the national team before 2018."
