The historic scoreline matched the thumping Sir Alex Ferguson’s Reds handed out to Ipswich Town at Old Trafford in March 1995, when Andy Cole scored five goals.
Against the Saints, the goals were shared between seven different United players, plus an own-goal as we took full advantage of a 77-second red card for Alex Jankewitz.
Ole Gunnar Solskjaer’s merciless side were 4-0 up at half-time with goals from Aaron Wan-Bissaka, Marcus Rashford, Edinson Cavani accompanying a Jan Bednarek own-goal.
In the second period, the ruthless Reds refused to ease up as we ripped into the Saints with a late onslaught that saw a further five goals.
