The Spanish global has upset a lot of people in Spain for his political views where he has been a supporter of the referendum on Catalan independence, and speaking after a match that very almost didn't take place, the toll it is taking on Pique was clear to see.
"For a moment I couldn't believe it", he told the AFP agency.
"Going with the national team is not a competition in patriotism, it's about trying to play the best you possibly can".
"If anyone in the federation believes I should not be there, I will step aside".

The 30-year old was clear about his position on the importance of their being a referendum saying that whether people voted yes, no, or abstained it didn't matter.
Of those to appear for the Camp Nou outfit, none were more affected by today's harrowing events in Barcelona than Catalan native Gerard Pique, who has always been an advocate for independence for the people of Catalonia.
