Arsenal failed to continue the pursue of winning the europa championship because they have plans of winning the Premier league which is the most important aim for them. At first in the Europa League they were doing very well but because of too much pressure they couldn't maintain good performance in europa.
It’s very disappointing Arsenal got eliminated from the Europa league. I think Arteta didn't show much interest in the Europa league title when they faced Sporting almost a weak ago, I really don't like the idea of intentionally dropping out of cup competitions with the aim of keeping the squad fit for a particular trophy (EPL), now how will Arteta face the world if Arsenal fail to win the premier league title.
I can understand how you feel, and I am no exception. As fans of the Gunners, we hope that Arsenal can get rid of Sporting, especially since the game will be played at the Emirates Stadium. however, when referring to the starting line-up that Ateta took down in that match.
To be honest, I feel that Arteta is not prioritizing the win over Sporting. because some of the core players for the midfield sector were not played. in particular, Odegaard who has usually been an important player for the Gunners squad.
The sign of Arsenal's defeat seemed to have been seen in the early minutes of the first half, when Tomiyasu was pulled out in the 9th minute who had a bit of a problem with his foot. plus, followed by pulling out W.Saliba in the 21st minute. losing these two players, automatically made Fabio Vieira not have support from the defense to build attacks. as a result, Arsenal were not able to play optimally.
However, with Arsenal slipping up in the Europa League competition. Arteta will focus his team more on the Premier League, it was proven that they performed optimally against Cystal Palace. I hope Arsenal appear consistent and stay on track to win in their domestic league. well by the way, the fall of Arsenal made United the strongest challenger in this competition.
