Liverpool & United could join foces over common enemy
It won't happen because most Liverpool fans are happy the Manks are in trouble and vica versa. There is no shared feelings here other than the obvious hate for the other club. You'll find most fans of both clubs are hoping that their rival bites the dust first.
I find that view a bit closed minded and it would create a perfect opportunity to double our/your ranks and create a louder voice for both clubs to benefit from.
