The Blues ran out convincing 2-0 winners over Arsenal in their Premier League clash at the Emirates Stadium on Sunday. A goal on his second Chelsea debut from Romelu Lukaku was added to by a fine strike from Reece James to seal the deal.A statement win from @ChelseaFC 🔵#ARSCHE pic.twitter.com/KUTqolj9b9— Premier League (@premierleague) August 22, 2021The visitors wasted little time in assuming complete control of the tie, taking the lead through Lukaku in just the 15th minute. James’ effort in the 35th minute then doubled their advantage as the hosts looked to have no answers for a Chelsea side in full flow.The second half was a more even contest as Arsenal made a fist of it, but Chelsea’s lead was never in any real doubt. They claimed all three points and secured another clean sheet in the process as well. On that note, here are the hits and flops from the game.#1 Hit: Reece JamesJames shone at right wing-back as he notched a goal and an assist in the gameJames enhanced his reputation as one of England’s premier attacking full-backs with an all-round display that included a goal, an assist and several strong tackles and interceptions.The young Englishman made full use of all the space he was afforded down the flank, particularly in the first half. He set up Lukaku for the opener before adding the second himself within 35 minutes. 1+1 - Reece James is the only second Chelsea player to score and assist away from home against Arsenal in the Premier League, after Juan Mata in September 2012.

He did well to keep Arsenal in check as and when they advanced down his flank. Like Marcos Alonso on the opposite flank, James seems to be thriving as a wing-back in Thomas Tuchel’s three-at-the-back system. He is sure to be a threat at both ends of the pitch this season. #2 Flop: Bukayo SakaSaka (R) had a disappointing outing against ChelseaOne of the undisputed stars of England’s excellent campaign at the Euros, Saka is widely expected to inspire a similar series of positive results this season at Arsenal.Unfortunately for the Gunners, Saka does not seem to have shaken off the after-effects of his exertions over the summer. H delivered a lackluster performance in his first start of the season.Stationed out on the left wing, the youngster displayed a lack of match sharpness with a couple of loose touches in the final third. It caused a few of Arsenal’s attacks to fizzle out disappointingly. Furthermore, Saka’s dereliction of his defensive duties afforded James far too much space down Arsenal’s left flank, which played a major part in both of Chelsea’s first-half goals.Saka’s showings are sure to pick up over the course of the season. But this performance against Chelsea was far from what Mikel Arteta and the Arsenal faithful expected from him. His substitution on the hour mark was quite justified.
