Bayern Munich really surprised me in the previous game and I believe they’ll qualify to ½ finals.

When Arsenal scored the first goal within the first minutes I thought that was it for Bayern, due to Arsenal’s ability to keep clean sheets even against strong opponents. This, combined with the fact Bayern would be forced to play more open, made me think it would be more likely for Arsenal to score the 2-0, than for Bayern to draw.

However, Bayern flipped the script, paradoxically, by not changing their approach. Despite the 0-1, the players kept a cool head and Tuchel also remained calm, showing a huge experience and confidence in their plan: the tactical approach didn’t change at all. Arsenal didn’t manage to dominate the game as it was expected, they had possession, but for most of the game, it seemed that Bayern was in control of the situation.

I felt Bayern troubled Arsenal's defense more than other teams have managed lately, with the speed and directness of Leroy Sane catching the Gunners out on several occasions.

Harry Kane was very motivated, scored a goal and I think will be important also in this second leg, having chances, especially if Jamal Musiala and Sane are performing at a high level.

Tactically, I think Tuchel beat Arteta because Bayern was able to play the way they wanted, without sacrificing their attack, and despite having 60% possession, Arsenal never looked comfortable on the ball and wasn’t able to create many chances. Arsenal had 1.18 expected goals and Bayern 2.09.

Bayern stopped them from being able to build up through the center of the pitch, and instead forced them to progress the ball with Kiwior or White, forcing Odegaard and Havertz to drop deeper and closer to the flanks in order to progress the ball, putting them far from the dangerous zones.

Bayern dropped deep and defended when they had to, but mostly used a mid block. This didn’t mean they would sacrifice attack. The main difference with some previous matches was that the attacking phase was more controlled, more “responsible”. Instead of piling men forward, Bayern attacked intelligently, forward runs and passes were much more careful, the rest of the defense was always correctly positioned, anticipating that Arsenal could easily take advantage of any counter-attack.

For Arsenal to counter effectively, they need to be quick and accurate in the transitions and Martin Odegaard will be vital in that regard. His incisive passing to the forwards ahead of him could hold the key to unlocking the Bayern defence.

So what did Arsenal learn? Champions League is really hard and they’re not equipped with the maturity to deliver like other clubs that remain are. Their manager Arteta lacks experience and so do their players. People don’t like that comment, but it’s a reality. Cup comps at this level are really, really tough. The general approach for Bayern should be the same; be organized and compact on defense, and quick to take advantage in transitions, as Arsenal’s back line is quite slow, especially the defensive midfield.

Bayern Munich is not done, at least in the Champions League. This game could be more important for them, as are out of all competitions and this tournament is their only chance to win a title this season. Arsenal is involved in the Premier League title race and this is affecting their performances, as seen at the weekend in the defeat against Aston Villa.

拜仁慕尼黑在上一场比赛中真的让我很惊讶，我相信他们能晋级半决赛。

当阿森纳在开场的几分钟内打进第一球时，我认为拜仁就完蛋了，因为阿森纳即使面对强大的对手也能保持不失球。这一点，再加上拜仁将被迫打得更开放，让我认为阿森纳更有可能打进2-0，而不是拜仁打平。

然而，矛盾的是，拜仁没有改变他们的战术。尽管0-1的比分，球员们都保持着冷静的头脑，图切尔也保持着冷静，他对自己的计划表现出了丰富的经验和信心:战术方法根本没有改变。阿森纳没有像预期的那样控制比赛，他们有控球权，但在比赛的大部分时间里，拜仁似乎控制了局势。

我觉得拜仁最近比其他球队更容易给阿森纳的防线带来麻烦，勒罗伊·萨内的速度和直接在几个场合抓住了枪手。

哈里·凯恩非常有动力，进了一个球，我认为在第二回合也很重要，有机会，特别是如果贾马尔·穆西亚拉和萨内都有高水平的表现。

从战术上讲，我认为图切尔击败阿尔特塔是因为拜仁能够在不牺牲进攻的情况下打出他们想要的方式，尽管控球率为60%，但阿森纳在控球时看起来从来都不舒服，也无法创造很多机会。阿森纳预期进球1.18个，拜仁2.09个。

拜仁阻止了他们在中路的组织，而是迫使他们在基维尔或怀特的配合下带球向前推进，迫使奥德加德和哈弗茨往边路更深处更靠近，以便带球向前推进，使他们远离危险区域。

拜仁在必要的时候会进行后撤和防守，但大多使用中路封盖。这并不意味着他们会牺牲进攻。这场比赛与之前的一些比赛的主要区别在于进攻阶段更受控制，更“负责任”。拜仁没有把人堆在前面，而是聪明地进攻，向前的跑动和传球更加小心，其余的防守总是正确地定位，预料到阿森纳可以轻易地利用任何反击。

对于阿森纳来说，要想有效地反击，他们需要在转换中快速准确，而马丁·奥德加德在这方面将是至关重要的。他犀利的传球给前方的前锋，这是打开拜仁防线的钥匙。

那么阿森纳学到了什么呢?欧冠联赛真的很难，他们不像其他俱乐部那样成熟。他们的主教练阿尔特塔缺乏经验，他们的球员也是如此。人们不喜欢这样的评论，但这是事实。这种级别的杯赛真的非常非常艰难。拜仁的总体策略应该是一样的;在防守上有组织和紧凑，并能在转换中迅速利用优势，因为阿森纳的后防线相当缓慢，尤其是防守中场。

拜仁慕尼黑还没有完蛋，至少在欧冠还没有。这场比赛对他们来说可能更重要，因为在所有的比赛中，这场比赛是他们本赛季赢得冠军的唯一机会。阿森纳正在争夺英超冠军，这影响了他们的表现，就像周末输给阿斯顿维拉的比赛一样。
