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.
How it's possible you're saying Arteta didn't interested with Europa league? Arsenal were trying as their best to score a goal during extra times, but Sporting CP's goalkeeper just good enough to save a ball. Arsenal's goalkeeper e.g. Ramsdale keep making blunder and doesn't good to save a ball, it's better for Arsenal is looking for other goal keeper. Actually Matt Turner is better than Ramsdale, but Arteta doesn't use him to play.
Arteta wants to win both the Premier League and Europa League titles. And Arsenal has the ability to win both of these titles. This is because Arsenal is not dependent on the performance of any particular player. Real Madrid is a strong team but they depend on Benzema's performance. Manchester City has plenty of star players, yet they are reliant on Haaland's performances. But Arsenal are very stable as a team. The team is not dependent on the performance of any particular player. And so they have the potential to win both the Premier League and Europa League titles.
