Sorry but that's nonsense. They could have easily taken care of any number of teams who's played here in Scotland in European competitions of late. I can think of an Albanian and Welsh teams who we've been up against for starters. I think you're over playing this 'Celtic are terrible' card.
Its great that they're not having the best spell right now, but you're kidding yourself on if you think they've suddenly turned into Hamilton Accies over night.
