Chelsea defeated Aston Villa 2-0 at Villa Park.

Graham Potter made it five straight victories in all competitions and remained unbeaten as Chelsea manager with a 2-0 victory over Aston Villa on Sunday at Villa Park.

Aston Villa vs. Chelsea: Critical factors

When Edouard Mendy sustained an injury, Chelsea supporters probably feared the worst. But Kepa stands up to repay Potter's faith.To keep his team ahead, Kepa made some outstanding saves in the first half in recent games. Kepa, who has received a lot of criticism in recent years, has surpassed Mendy in the standings, and his prowess with the ball seems to fit Graham Potter's style much better. Most importantly, he appears to have developed his presence and shot-stopping skills.

Villa's worst adversaries are themselves:

Steven Gerrard will think Villa are now beating themselves. A better shot would have seen them rightfully level at halftime, but Tyrone Mings' terrible error allowed Mount the opportunity to give Chelsea the lead. These kinds of events are likely to occur when your luck is bad and your confidence is low.

Mount is performing at his peak again:

In his previous three games for Chelsea, Mount has recorded two goals and three assists, demonstrating that he is returning to form. The English playmaker is a great fit for Potter's style of play. He shows up in risky situations, ties things together nicely, and is designed for the fluid style of play that Chelsea will use under Potter. Mount will be one of the key players moving forward if Chelsea is to succeed under Potter.

Strategic emphasis

Because they moved less smoothly and appeared a touch disconnected, Chelsea's back four didn't really function. Even so, they were dangerous when they broke, and that was sufficient. Villa played far better in the first half, but they were unable to capitalise on their opportunities, which cost them dearly.

Stars of the event 

Kepa Arizaba: Wonderful stops in the first half held off Villa. Considering his chances in light of Mendy's injury.

Mason Mount: A nice finish on his first and a great free kick that caught Martinez off guard.

Leon Bailey: Chelsea looked quite shaky when he had the ball and caused a lot of issues with his spiffy runs.
