Three reasons why Chelsea beat Southampton 4-1 | Premier League 2019-20

#1 Abraham and Mount's purposeful start

Mount celebrates his goal having worked tirelessly to retrieve possession in the So'ton half.

Tammy Abraham has silenced critics to prove his worth as Chelsea's first-choice forward option in recent months but Mason Mount's adaptability, invention and persistence means the pair have combined to develop into one of the duos to watch in the league this term.

Sure, it's still early days but all the signs are promising from two players with plenty of potential to fufill and a manager in Frank Lampard that will provide them ample opportunity to blossom.

It was far from a vintage display by either but crucially, they did what they could to get Chelsea going early on. From there, they found themselves in cruise control courtesy of the Saints' lax defending and a comfortable away cushion to protect.

Mount's passing was risky and the stats show that (28 accurate passes, 68.3% completion), though the 20-year-old playmaker created two key chances and displayed composure to double the lead with Southampton still stewing from the frustrating way they conceded their first. He could've completed his brace three minutes later, but fired an effort over the bar after good work from Hudson-Odoi.

Abraham meanwhile, was an ever-present thorn in the hosts' back-line and despite registering just 23 touches in 84 minutes, showcased precisely why he scored goals for fun on-loan in previous seasons elsewhere.

Attacking intelligence, awareness and precise movement were key as he broke the deadlock and continued to pull So'ton defenders left-and-right trying to track him later on. Both were replaced late on by Kovacic and Batshuayi respectively, presumably with their latest England call-ups in Lampard's mind after the pair delivered another memorable shift.
