Barcelona defender Gerard Pique was again jeered during Spain's 4-0 win over Luxembourg last night.
Pique defended himself at the final whistle, insisting he didn't deserve such treatment.
"You have to ask the public; I only like talking about what I do out on the pitch. I thought I put in a good game, the result puts us on our way to France and now we want to do a good job at the Euros.
"I seem to have explained myself a thousand times on this... no one should be in any doubt about me and my commitment; I've been with the national side since I was 16. People can take a look through the archives and see everything I have said in the press since I was a kid. You won't find anything bad, or comments I've made against the national team or this country for people to get upset about."
