Spain: the world's best international team, the current reigning World Champions and double-winning European Champions.
A squad forged from the finest players on the globe playing in the top leagues on the continent; a wealth of experience, an admirable style of playing and the mentality to come back and prove they are the best, time and time again.
An irreplaceable and perfect force of football then?
