Villarreal and Celtic have a little bit of history, having played a very friendly UEFA Cup quarterfinal matchup a couple of years ago. In the matches, the clubs and followers took it upon themselves to provide an example of true European comradeship, with peace in the stands and respect on the field. Since then, even a local group, the Penya Celtic Submari has been formed, where fans support both clubs. Many Celtic supporters have been around since last Wednesday, where they made their presence felt at the match against Racing. Hopefully the clubs will be able to keep it up.
