#4: Manchester United's sturdy defence
You have to give credit to the way Jones and Bailly have been performing for the Red Devils this season. Perhaps their partnership is the most crucial factor in United's defence.
United have the best defence in the Premier League by far, with 8 clean sheets out of 10 games and only 4 goals conceded. Considering Chelsea's underfire attack, the stats itself are a sign of worry for Antonio Conte's men.
Alvaro Morata has gone scoreless in the last six games in all competitions and Pedro has only 2 goals to boast in the 6 PL games he has featured in. Marcos Alonso and Cesar Azpilicueta will try to add support on the flanks, but the duo will find it tough against Valencia and Young, who were stand-out performers against Tottenham last weekend, nullifying the threats from Serge Aurier and Dele Alli.
With such a sturdy defence to face, the Blues will find it hard to break the deadlock with their 52% shot accuracy against weaker defences than United this season. Even if they find the breakthrough, they will be put to the test against the world-class David De Gea.
As a result, the pressure piled on Chelsea due to the number of unsuccessful attempts will certainly help United in dominating the game against Conte's men.
