I can imagine Badass getting beaten in Glasgow for showing off as a Juve fan.
Then again, I can imagine him getting beaten in Turin too, on the return match. Something like:
Badass: [hmmm, there are some Juve fans there, I'll see if they can sell me tickets] Hi, me no speak Italian, but do you sell tickets?
Juve fans: Eh?
Badass: Do you Celtic(ets)?
Juve fans: You Celtic?
Badass: Celtic(ets), yes, yes, yes, do you Celtic(ets)?
This might happen.
