No dude, I don't think we are underestimating them. we know what we're up to. It's not like we think we're gonna play pescara there, they are as good as any 2nd tier team of this competition ( Valencia, Gala, Schalke, etc.), we know if we approach the game with the right mentality, control it and impose ourselves, then we'll see ourselves going through.
It's those celtic loonies that are delusional that think they have one hand on the trophy already.
And it's hilarious.
