The Blues continued their 100% start to the new season with a thrilling 4-3 victory over the Seagulls. Chelsea’s star studded attack again offered a tantalising glimpse of the threat they will offer over the course of the next nine months. Cole Palmer looks somewhere near back to his best and has struck up an instant rapport with Morgan Rogers, while Joao Pedro finally appears to have ended the club’s search for a dependable No.9.

At the other end, however, the defensive frailty that has plagued Chelsea over the past couple of seasons was again in evidence, despite the presence of new goalkeeper Emi Martinez who was making his debut following a move from Aston Villa. With five goals conceded in two matches, Terry acknowledges that level of defensive generosity is unsustainable and improvements are required ahead of Sunday’s meeting with title rivals Arsenal. The former Chelsea captain told his YouTube channel: ‘As good as the attacking play was I think we have to look at the defence and I’m sure the manager will in the next few days.
