Celtic should do and say nothing. Legia Warsaw have made a simple, and very costly, administrative error. UEFA have upheld the rules of the competition.
There is nothing Celtic can do or say to change the situation, even if they wanted to. And why should they? What would you want Thistle to do in this scenario? Millions and millions of pounds are at stake.
Celtic were sh!te. They suffered humiliation over 180 mins and we all had a good laugh. The history book, though, will show that they won on away goals before being humiliated again in the next round.
Let's hope they continue to keep us amused after their hilarious gig at the Edinburgh Fringe.
