Such was Alex Ferguson's determination to "knock Liverpool off their perch", Anfield was often the scene of the Scot's angriest moments as Manchester United manager, according to Gary Neville.
Ferguson famously described his biggest challenge as eclipsing Liverpool's 18 top-flight titles, something he achieved before retiring in 2013 as United moved onto 20.
Throughout his Old Trafford tenure, Ferguson was renowned for dishing out the 'hairdryer' treatment when unhappy with United performances.
And Neville says the worst of those outbursts always seemed to come at the home of their fierce rivals, where United travel this weekend in the Premier League.
"Sir Alex was always different around the big games," the former United skipper said on Sky Sports.

"He could not stand losing at Anfield - and if we won there, it didn't matter how we played - it was like the best thing in the world."
