Madrid last season you mean? Doubt anything will come out of it. Sure they dived for a lot of penalties, scored offside goals and had the other teams onside goals called off but I don't think there is enough evidence.
Young, Welbeck, Nani, Valencia dive every day all day for Manchester United, lets start calling them cheats who kill the game. Oh no wait, I am older than 14.
Meh take it lightly, probably 90% of the supported teams in this thread have been knocked out and beaten by Barca at one point or another in the recent years. Whether its in a Semi, a Final or League, the rest you can figure out on your own.
You guys can say this sounds arrogant or stupid or whatever you want, but no-one ever reacts like this when Chelsea, M.United, Juve, Milan, Man City, Bayern etc ever "cheat".
