I get where you're coming from min but none of the teams you mention won any of those games - on aggregate Saints lost 6-3 to Monaco, Raith 4-1 to Bayern, Well 3-0 to Dortmund.
The problem is that your argument is based on the premise that we will lose the game anyway, so better to lose it to a more glamorous name.
I'd much rather actually progress in the competition than revel in short-lived glorious failure in the first round, it feels too much like the football equivalent of the elderly pub drunk mumbling about how he "could've had" the hulking punter that's just laid him on his arse.
Anyways, if we reach the group stages we both may get to have our cake and eat it - progress in the competition AND an arse-kicking from some more glamorous names into the bargain.
