Arsenal have won each of their last nine home games against Burnley in all competitions but on Sunday, the Clarets found their way through at the Emirates.In an uneventful first half, Chris Wood came closest to scoring for the visitors while Alexandre Lacazette forced a quick reflex save from Nick Pope. Out of the combined nine shots from both teams, only one of them had been on target.The Gunners started well in the second half, with players moving the ball a lot faster, playing at a higher tempo, and creating more chances for Bukayo Saka and Pierre-Emerick Aubameyang.Unfortunately, Granit Xhaka's red-card offence in the 58th minute affected the game-plan. Within 20 minutes of his dismissal, Burnley were a goal up thanks to an own goal from Aubameyang. Instead of clearing the corner, the striker headed the ball into his own net, and that was the only goal of the fixture.With that victory, Burnley got out of the relegation zone while Arsenal are just five points away from safety. On that note, here are the five talking points from the game.#5 Arsenal's lack of threat in set-piecesWillian disappoints for Arsenal againThere were seven corners in the first 45 minutes for Arsenal, but none of them resulted in shots on target. Every single effort came to nought as the Gunners tried to play things safe and were too afraid of taking risks.Without Nicolas Pepe in the Premier League team, Willian has been tasked with corner duties. However, the Brazilian struggled to make an impact alongside Hector Bellerin.It was extremely frustrating to watch the scenes of the half-hearted play and regardless of what the players did, their efforts were simply not good enough. The threat that the Arsenal attackers once had has been missing for a long while.As it stands, it appears that no player in the club is confident that they can get a favourable result in the Premier League.#4 Arsenal need creative midfieldersThere is an astounding lack of creativity in the Arsenal teamWhile teams like Liverpool and Leicester City are getting some headway with their crosses, the similar style of play isn't working for Arsenal, and Arteta isn't willing to give up just yet.The game is desperately calling out for the 38-year-old to bring in a creative midfielder in the middle of the pitch when everything else on the flanks fails. However, the manager went into the season without a backup plan.Willian has attempted 30 crosses in his last two Premier League games for Arsenal:◉ 2/16 completed vs Spurs◉ 3/14 completed vs BurnleyStruggling to find that end product. 😬 pic.twitter.com/ufRf5U9Iei— Squawka Football (@Squawka) December 13, 2020Currently, Mesut Ozil is unavailable for selection and as such, Arteta can only name youth stars Joe Willock and Emile Smith Rowe on the bench. Both performed decently well in the mid-week UEFA Europa League game but surprisingly, they had no role to play against Burnley.Should Arsenal not sign any creative midfielders in the January transfer window, they can bring Ozil back into the squad next month. The German midfielder only has a few months left on his Arsenal contract but he is determined to play again and is already making his intention of playing known on his social media.Need help @Arsenal? 😉❤#YaGunnersYa— Mesut Özil (@MesutOzil1O88_) December 13, 2020
