Ayoze Perez and Jamie Vardy hit hat-tricks as rampant Leicester demolished 10-man Southampton 9-0 to equal the biggest win in Premier League history.
Brendan Rodgers' impressive Foxes registered five first-half goals at St Mary's en route to inflicting the heaviest defeat in Saints' 134-year existence and move second in the table.
Strikes from Ben Chilwell, Youri Tielemans and James Maddison completed an astonishing scoreline as City emulated Manchester United's 9-0 win over Ipswich in March 1995.
During a history-making night on England's south coast, Saints defender Ryan Bertrand became the first top-flight player sent off following a VAR review after a dangerous lunge at Perez in the build-up to Chilwell's 10th-minute opener.
The early dismissal undoubtedly had a significant impact on the home side's fortunes but it could not excuse the embarrassing - and record-breaking - capitulation which followed.
Southampton's previous worst defeats on home soil were 6-0 reversals to Plymouth in 1931 and Brentford in 1959.
The thumping loss also surpassed three 8-0 defeats on the road, the most recent of which came against Everton in 1971.
