I've always said Real Madrid to me are an amalgamation of the worst features of Utd, City and Chelsea.
Three clubs that I think most (British) neutrals would find it hard to support. Utd probably more for their legions of glory hunting/retarded fans. The other two have less class than a used condom and seem to delight in being a rich mans play thing.
As for Bayern, I cheered for them in 99 and will have no problem doing it again.
