Arsenal are capable of very good performances, Arteta has been able to create a very good attacking line this season, but at the moment it all depends on City. Arsenal can win all their remaining games with the same crushing score, but if City can win all their remaining games without losing a single point, this will make them champions. It is obvious that Arteta focused specifically on the Premier League, since I see that they play better here than they did in the Champions League. Either Arteta tried to use different tactics in the Champions League, or he felt more responsibility, I don’t know what the reason is, but in the Premier League they play much better.
As you say, it's clear Arteta is specifically focused on the Premier League. However, because Arsenal advanced to the quarter-finals, Arteta had to divide his focus into two competitions at once. For the Premier League in particular Arsenal is really targeting it, in the Champions League Arsenal will appear to play as well as possible to the extent they are capable of. in both the Premier League and Champions League, Arteta always uses the same pattern but obviously different tactics depending on the team he is opposing. in the Premier League is the main goal, especially since all teams have to play 38 matches until the end of the season. In the Champions League, not only is a team strong and good, but the luck factor also plays a big role. The proof is that Arsenal was able to play well against Bayern Munich both home and away. Unfortunately, Joshua Kimmich's goal in the 63rd minute buried Arsenal's progress to the next round.
So, Arteta is back to focusing on his main goal of the Premier League. beating Chelsea with a landslide score made us happy, not just the goal but the pattern and play that Arteta implemented. Their current goal is that Arsenal must wipe out all matches with a win, and let the final result decide the rest. If City and Liverpool have to win game after game, then that's what happens. specifically, Manchester City. but if these two teams have to slip up, then that will happen and this applies to Arsenal too.
Let's just enjoy every match presented by the Premier League. If City is able to sweep the match clean with a win, then they deserve to maintain their ranking. Early this morning in my country, Manchester City will play their match away to Brighton. theoretically, City deserved to win the fight. but if there is a surprise, of course we will be very happy as fans of the Gunners.
