This match was enjoyable, even if the individual displays were perhaps a little shambolic at times. If we took away one thing from Saturday’s contest between these London rivals, it’s that both Chelsea and Arsenal are some way off challenging for the title.

More wayward defending of the likes they served up could dent their aspirations this season even this early on in their respective campaigns.

It took a late winner from full-back Marcos Alonso to divide these teams as Chelsea, champions of two seasons ago, added this victory to the one over Huddersfield Town on the first weekend.

Meanwhile, Arsenal’s new manager Unai Emery still awaits his first league victory as the north London side experience their worst start to a season since 1992. Life in the post-Arsene Wenger era will take some getting used to.

Emery’s opposite number, Maurizio Sarri, the new Chelsea boss, may have a perfect record after a good start to his time at Stamford Bridge. However, even he reflected on a poor defensive display from his side that saw Arsenal claw back from two goals down.

“We did very well in the last 25 minutes today, but I think we have to work,” said Sarri, when asked if he thought Chelsea offered the potential of champions.

“We have to improve in the defensive phase and I'm not talking about only the defenders, but all the players. So I think we have to work and we need to improve.”

Eden Hazard may have only come on for the last third of the match but the Belgian playmaker, his future still unclear, made the difference as he created the winning goal for Alonso.

Chelsea dominated the early exchanges at Stamford Bridge, with their opponents rarely threatening in what had started as a one-sided contest. 

Chelsea winger Pedro put his side on the way in the ninth minute after firing the opening goal. The home side were rampant as the opposition struggled.

Even when Arsenal did find the breakthrough, as they did on the 19th minute, striker Pierre-Emerick Aubameyang blazed over.

Moments after that chance, Alvaro Morata burst through Arsenal’s back line, turned Shkodran Mustafi before firing low beyond Petr Cech.

However, Arsenal hit back, through Henrikh Mkhitaryan, on 37 minutes and Alex Iwobi four minutes later as Chelsea’s players undid all their good work.

Chelsea took the win late on, however, when Alonso applied the finish to a move inspired by the superb Hazard as Arsenal were condemned to yet another defeat.

Emery said: "The second half was when we needed to control the game and create chances, but in the second half we didn't push, or keep possession, and we gave them options to score.

“We had opportunities but didn't take them, they did take them.”
