My issue would be that we could playing a Cup Final on the 30th May and then a qualifying round of the Europa Cup in the first week of July, which leaves rest and a break for the lads limited and pre-season compromised....
I understand the attraction, but we have a small squad already, with out even a bonafide main striker on a permanent deal....would a friendly in say, Lille, not suffice?
Even if it did compromise us for one season, IMO it would still be worth it. Surely the whole point in doing well in the league is so that you get into Europe.
