Manchester United fans have made their feeling known at half time as Liverpool head in at the break with a 2-0 Old Trafford lead.
Clashes between these two rivals are etched in Premier League folklore with United finding themselves on the back of some humbling results in the Jurgen Klopp era.
Arne Slot's first trip down the M62 opened a new chapter in the rivalry with the Dutch coach winning his first two games as Liverpool boss this season.
Luis Diaz's two goals have put Liverpool in the driving seat but the Red Devils faithful have focused their anger on one of their own at the break.
Brazilian veteran Casemiro was partially culpable in the build-up to both of Diaz's goals and United fans were seen berating the former Real Madrid man as he headed down the tunnel.
Casemiro has since been replaced at half time by academy product Tom Collyer.
Erik ten Hag faces a crunch half time team talk, as he aims to turn the game around, with Slot pushing to become the first Liverpool boss since Bob Paisley to win a first game in charge against United, as he beat them 3-1 in November 1975
