Basically Arsenal became one of the teams that had a high transfer value and thus, it was proven at least in the last two seasons that Arsenal managed to compete for trophies in the Premier League. After all, if for example Arsenal were unable to do that, then Arteta should have been fired. But yes,because so far Arteta has still managed to make Arsenal have a good performance and although there is no trophy obtained by Arsenal, but at least there will still be a chance for Arsenal to get the best results next season maybe with a trophy too.
We await what Arsenal can do in the next season, they’ve really tried their best for the past two seasons and their performance have been very impressive to have won at least a league or any other trophy in one of the competitions they’re participating in. They need to always be at their best if they want to win a trophy and not like other seasons that they perform a bit impressive and after a while their performance retard and give the league away to another team. Arsenal are worthy of being champions by now since Arteta took charge, maybe they can be able to prove that sooner enough.
But about the big win Arsenal got against Bayer Leverkusen, I personally don't consider it a good or impressive result because after all, they only play in friendly matches that cannot be used as a reference. After all, if you compare the victory against Bayer Leverkusen,then of course Atalanta is still the best, because Atalanta managed to beat Bayer Leverkusen in the Europa League final, unlike Arsenal who only won in a friendly match. lol
Friendly matches are sometimes not rated good enough to for a te to know their stance against another team, but it can also play an important factor in determining whether the teams are capable of having to give the other a tough time when they meet head-to-head. Bayern Leverkusen are champions of the Bundesliga and Arsenal are runner ups in the premier league, both of them can show a great performance against each other when they meet.
