Mourinho's Chelsea used different tactics for the match against Liverpool and City*. 4-3-3, defensive tactic. His normal tactic which he'd use against every team at home is different. (He parks the bus only in away tough games).
I'll try my best to replicate.

Go Route one and Drop much deeper would be wrong IMO, he was still using wingers instead of lumping the ball up.
Also his tactics against City would be different, as he did not completely concede the midfield a la "Stand off opponent" as he had full stretch squad. Nor would that be narrower and it'd be "Counter" instead of defensive.
However, I don't think this will work as ideally as it did in real life, as opposition somehow finds a way to penetrate in the game if you go defensive.
Mourinho usually prefers ferocious pressing while not hogging the ball, forcing opposition mistakes, but in certain matches he likes to concede the midfield for positional advantage, much like Real Madrid did to Bayern recently.
You could also use one of CMs as CM defend, but Matic ventured forward fairly regularly, completing 5 take ons.
