Everything can still happen to them and the worst possibility such as injury must be anticipated from the start because it is clear that currently there are several clubs who have experienced the severity of the injury storm which has made it difficult for their clubs such as Chelsea in wading into the EPL and of course Barcelona who must return to Europe. League due to injuries to their players.
Currently Arsenal are in very good condition so they have to anticipate all bad possibilities for them to continue to be consistent in the EPL and Europa League.
I believe Arsenal are one of the favorites in the Europa League this season. Their game is very good and I watch their game more often every chance I get, it's very entertaining. But you're right, player injuries are the most likely worry that every team thinks about right now given the very busy schedule.
But for now the round of 16 matches are still very far from Arsenal. They still have time to stay focused on the Premier League while waiting for who will be drawn for the next opponent. So it's still safe to say Arsenal are the favorites if they're only going to meet weak teams in the last 16.
Arsenal will be counted as the favourite considering their performance which is quite stable on premier league or europa league but their opponent hasn't determined yet so they have to wait the results of play off matches but Arteta has aware the possibilities Arsenal will meet the teams who eleminate from Champion league such as Barcelona or Juventus so probably in the round of 16 Arsenal will meet strong opponent and this makes Arsenal journey will be more hard to achieve the trophy but although Arteta didn't promised the trophy but he said Arsenal will attempts to get good achievements on europa league but indeed it's difficult to focus to several different competitions and probably Arsenal main target is premier league
Maybe it's a safe scenario where the Arsenal squad doesn't get injured players, but going forward we won't know for sure. Well, if later one of Arsenal's key players gets injured then of course this will immediately have an impact on Arsenal's performance, both in the European League and also in the English Premiere League.
Because basically Arsenal's pressure is high, with Arsenal still at the top of the Premier League standings, of course Arsenal are required to be able to always play well.
This will at least make their fitness maybe a little less than optimal so yes, I personally am still not so sure that Arsenal will be a strong candidate in the hunt for the Europa League title this season.
Due to the fact that Arsenal does not have good quality substitutes, so to close this gap, maybe Arsenal will find it difficult to maintain their performance. So far, Arsenal have been very good and consistent in making quick goals but unfortunately, when they get a goal back or concede first, sometimes Arsenal seem to have a deadlock to be able to lead the match.
But let's just wait and see what will happen, because at the same time the big teams who left the Champions League and played in the Europa League are getting back to their best form. This recovery will certainly make the competition to win the Europa League this season very difficult, because the competing teams are also big teams who have a high winning mentality.
