#2 The Sarri-ball effect
Chelsea's propensity to keep possession allowing their opponent to wear out as well as the high pressing tactics has been the hallmark of the Italian manager Maurizio Sarri.
So Chelsea will have to patient, passing the ball fast to exploit any holes or gaps that United might create as the game wears on. Sarri's tactics could well turn out to prove the deciding factor of this high profile clash.
