Mount and Pulisic’s positioning causes Arsenal problems
Key to Chelsea’s bright start was Mason Mount and Christian Pulisic finding pockets of space behind Arsenal’s midfield, and in front of their back three. The opening goal was a perfect example. Pulisic found space and drove at a retreating Arsenal back three. He then found Mount and when the ball found its way back to Pulisic he was still in front of Arsenal’s two central midfielders to score. Arsenal adapted by having a wing-back jam in and a centre-back stepping up – as in the final picture on the right, as well as pushing their wing-backs forward to reduce Chelsea’s options. That limited a real outlet, although Pulisic’s injury was significant.
