Two most successful English clubs. Political, cultural, and football rivalry. No direct transfers since 1964. "I'm not from Manchester but I hate Liverpool" — Gary Neville.
Transformed by City's 2008 takeover. Balotelli's 'Why Always Me?' Rooney's overhead kick. United 4-3 City (Owen 96th minute). Aguerooo.
The Roses rivalry. Goes back to the War of the Roses (1455-1487). Football expression of Yorkshire vs Lancashire.
