To be fair Villarreall had the best spell in their history on the basis of that run to the Cl semis, with 2nd and 4th place finishes and two more european semi finals following. And this from a team who had barely played top flight football before and never even reached a cup final in their history.
They were very unlucky with injuries when they were relegated as well, plus the financial landscape in Spain is completely on another planet to England.
