Played them in 2006 - Barcelona were European Champions at the time.
We definitely didn't play any of the winners of the past 20-30 years when they were champions.
I guess there's a possibility we could have got a cup draw or something against one of the English winners in the 70s or 80s, but seems like this is a first?
Bearing in mind the financial gulf between the European leagues and everywhere else, we're probably only a couple of weeks too early to catch them as (club) world champions as well.
