Chelsea midfielder Juan Mata admits he worries about his place in Spain's World Cup squad.
Mata has been used sparingly by Chelsea boss Jose Mourinho this season, which has put his Spain spot in jeopardy.
"The last word in making the squad is the coach. He knows my strengths and what I can contribute.
"It is true that I have had few minutes, but I feel fine. I'll try to do my best with my team and with the national team. It is impossible, this year, to not think about the World Cup and I hope that I can be there.
"From the age of 20 I've gone to all the major championships."
