I am not sure we do dislike Leinster - do we?
Test question.
English club plays foreign club. Whom do you support? (Generally speaking?)
That's all it is.
Depends who the two clubs are. I have a soft spot for Stade Francais and would always cheer them on (except against Quins of course). Cant say I have any real love of any other English clubs but would always cheer them over the Celtic sides.
