Sir Alex Ferguson said that his brief as Manchester United manager was to "knock Liverpool off their f*****g perch".
After over 2,000 games and 25 seasons, this year he finally succeeded.
Following an endless supply of trophies, none meant more to United's global legion of fans than their 19th league title - simply because it finally put Liverpool in their place.
It has taken Sir Alex 25 years to establish United as the leader of the championship pack.
When Alan Hansen captained Liverpool to their most recent championship in 1990, the tally read 18-7 in Liverpool's favour and few would have given the Scot a prayer of capturing one championship, never mind 12.
In '19' , award-winning journalist Harry Harris looks back at all the title winning seasons and analyses each one from the viewpoint of a player who distinguished himself in that title year, building up to the record title and an in-depth analysis of the 2010-11 season and how United finally surpassed Liverpool.
The book looks at the record through the eyes of those who took part in each of them, or who observed them from close quarters. '19' features exclusive interviews with Arthur Albiston, Alan Brazil, Steve Bruce, Garth Crooks, Gary Pallister, Paul Parker, Lee Sharpe, Gordon Taylor, Dave Whelan, Ray Wilkins.
