#2 Jose Mourinho - will he "park the bus"?
Jose Mourinho's fortunes in some ways have been contrary to Jurgen Klopp's. Whilst he has some top players under his stewardship at the club, he has had disputes with some players, is in contention with the board over transfers, and has showcased less stellar play and results in comparison to Liverpool.
They have lost to Derby County (of the Championship) in the League Cup this season, and secured Champions League qualification as much by luck as strong play.
However, Mourinho often gets results when needed, which buy him critical time and patience. A win vs the old enemy who are in a better holistic shape, would do much to settle fan dissent and unhappiness.
Would this mean he would park the bus though? It's possible. But doing this at Chelsea in his second spell relied on an immensely strong defence. His defence now at Manchester United isn't very strong, and relies in large part on de Gea's brilliance often. DDG could produce many good saves, but then with the attacking prowess of Liverpool, this may also be too much for them to handle.
A strong tactical plan by Mourinho would be enough to get a credible result here.
