I doubt that Arsenal can win this round, indeed both teams still have the same chance, but in the next match Arsenal will face Munich away, of course this will make Arsenal feel pressured and I'm not sure that even if Arsenal uses all their strength, Munich will also do the same thing, let alone competing at home will make Munich more confident to win.
If Arsenal can really improve with their attack, with how they were able to control the pitch in the first leg, I don't think they will be under pressure like that. Arsenal really played well in the last match, but the attack was not that strong. Arsenal were just doing touches on their own half-field side. They are making a lot of attacks, which was what I expected Arsenal to make in the first leg, but honestly, they were just driving back. With how Bayern Munich was playing, it is clear that Bayern Munich is not in that great form, and even from their own home game, I am not expecting much from them, but they will improve and play well more than the first leg game.
Infact, last match, it seemed that Bayern was just observing arsenal patterns of playing; it was counterattack tactics they were using with defensive, but with the pattern, I know Bayern Munich with is to play more aggressively at all angles to attack the opponent. Let's just wait and see what happens in the returning leg. Maybe Arsenal will have the opportunity to reach the reach the semi-final.
Basically, Arsenal still have to make big efforts in the Premier League, so it might be difficult for Arsenal to maintain their good performance at this moment in all competitions. Eventhough ofcourse, I admit that Arsenal is in a verygood trend at this moment, but Arsenal's position is also not completely safe in the Premier League standings and also in the Champions League. Therefore, it seems that there is still a possibility forArsenal to fail to get good results in one of these competitions. Because of course, it would be a big regret if in the end Arsenal failed in all competitions and in this way, Arsenal can maximize their chances of getting goodresults in one of these competitions by carrying out the right rotation ofcourse.
