#5 Jose Mourinho vs Jurgen Klopp
In spite of all these individual battles, it will come down to the managers' tactics. These tactics can make certain duels inconsequential due to change in formation, position and so on.
Mourinho is infamous for adopting a defensive approach against the bigger teams. 'Parking the bus' certainly did work for the United boss the last time he faced Liverpool, a game which ended 0-0. Considering the Mersey siders' hot form, one cannot really blame him if he adopts a pragmatic approach once again.
Klopp on the other hand, has found it difficult to break down teams who defend deep and are happy to let Liverpool have the ball. An open and flowing match is better suited for the German, but Mourinho will not do him any favours in that aspect.
Jose could also ask one of his midfielders to man-mark Salah, a tactic which he employed successfully against Chelsea's Eden Hazard - last season with Ander Herrera and with McTominay this season.
There are quite a few ways in which the game could pan out from a tactical perspective. One thing is for sure - the battle between the two adversaries in the dugout will be the most crucial in deciding the final outcome.
