They already surprised the world once in Paris so why they shouldn't do that again? But seriously PSG will play without couple of crucial players e.g. Kehrer, Bernat, Icardi, most likely Veratti and Marquinhos also won't play, considering the fact that Man Utd won against Newcastle last Saturday after decent performance and their only important absence will be Maguire I suppose those juicy odds are definitely worth a try, what do you think?
You basically said it word for word for the reason I picked United too, but only €5 haha. What odds did you get? I got about 54/10 on Fairlay, though it was almost 6/1 at some point (right now 5.92). You didn't get very good odds at 5/1 to be fair, all the other sites I'm looking at give a bit more than that! You should consider a switch;)
