Arsenal is not even in a good situation in Premier League and that's why I think we can't expect them to have good results in the tournament like Champions Legue.
Arteta is getting more experiacned and he id making progress but he is still far from a coach like Ancelotti with lots of experience in Chmapinos Leeague and tthat's why I think Real Madrid will have much more chance than other teams.
It is difficult to win the Champions League if the team does not perform consistently. Arsenal performed well from the start of the season, but their performance slowly began to decline which made many people, including me, doubt Arsenal's ability to win the Champions League trophy. Arteta has succeeded in forming Arsenal into a team capable of providing competition in the EPL, but he has not been able to develop a winning mentality in his players.
Arteta still needs to do a lot to bring Arsenal to win this competition, he must be able to make Arsenal appear consistent by maintaining their best performance in every game. The sharpness of the attack line needs to be improved and they need to always maintain a strong defensive area to maintain their lead. In my opinion, this season's UCL trophy is not for Arsenal because there are still many other strong teams who are ready to eliminate Arsenal from the UCL stage.
Arsenal's performance has been very poor and since Arsenal began playing poor games, I have lost faith in Arteta to win the competition because even in the Premier League, he can't win the title anymore he made a big mistake by allowing Liverpool to lead them in the table, and I do not believe Liverpool will lose any points now in the league because they are in good shape, and only Manchester City can stop them from winning the League Trophy this time.
I believe Arsenal will have a difficult time defeating Porto in the Champions League round of 16, based on how they are performing in their league. Arteta should wake up if he wants to win the competition but I don't think he will win this season he needs to perform better. I believe Real Madrid or Manchester City will meet in the final this time because I don't think Bayern or PSG can fight with Man City and Madrid this season. Barcelona is not in excellent shape and Napoli can defeat them, which is why i didn't list them.
