United out of Europe

I think Celtic were far better against barca this season tbh 2 0 home win, and considering the cost of their team v yours, it is especially untrue what you said

 

One was a group game the other a semi final second leg, are u really trying to compare them???!!

 

Both great wins, no doubt mate, but given what Celtic achieved over a superior team, we are talking performances not what stage of the comp, but nice distinction to further your argument
