Prediction
As Liverpool are favourites here, I believe they will win.
Nothing is impossible. United could pull off a shock if required, and this would be a boost for Mourinho and a serious negative for Klopp. Especially given the proximity between Liverpool and Manchester City on the table.
Moreover, Mo Salah is bang in form again, and their forward line vs Manchester United's defence would be telling.
Mourinho's best hope is a master performance from Pogba and his other top stars, or a tactical masterclass. If none of these materialises, it could be comprehensive for Liverpool.
Salah too would be keen to extend his place at the top of the PL scoring charts, and against his club's old enemy it would be a prime place to do it.
Should Man United lose here, it would be another critical blow in Mou's tenure at United, and in attaining top four and Champions League football next season. Would it mean the sack? Who knows? But it would worsen United's issues all the same.
It's not just a hate match or another episode of their mutual and longstanding rivalry - it's a definitive game in each other's season.
Final score: Liverpool 2-0 Manchester United
