I see Real Madrid as a strong favorite here.

They are in great form, playing great football and with very convincing performances. Won the 7 games played so far, including the UEFA Supercup, Champions League game against Celtic (0:3) and all league games.

Yes they are without Benzema, but the team has shown that they have more alternatives. Without him they have scored 7 goals in 2 games (0:3 vs Celtic, 4:1 vs Mallorca), with players like Vinicius or Rodrigo in great moment.

Coach Ancelotti made some rotations in the league game, leaving on the bench some players like Modric, Camavinga or Tchuameni in order to be at 100% for this game.

On the other hand, RB Leipzig is in really bad form. They were destroyed by a very poor Shakhtar (1:4) at home, while also lost 4:0 against Eintracht (who were outplayed and beaten 2:0 in the Supercup by Madrid) and 3:5 against Bayern Munich (similar level to Madrid).

Their bad performances at the beginning of the season forced them to change the coach, where the new one Marco Rose started with a solid victory against Borussia Dortmund this weekend (3:0).

The departure of Mukiele in the transfer market to PSG hurted them a lot, as he was a key defender and the club didnt sign any good replacement. Furthermore, other key defender (RB) Klostermann suffered an important injury in the ankle; so the team has a very weak defense for this season.

Key player Dani Olmo is out too due to a long term injury.

I think that RB Leipzig will try to make the same tactic as against Borussia Dortmund on the weekend (where won 3:0), playing a counter-attack game with fast players like Nkunku and Werner, and being dominated without making a high pressure. But Real Madrid is a team who knows very well how to stop counters and has many alternatives in attack when they are dominating.

There’s a huge quality difference here. Madrid is in great form, being very competitive and looks impossible to beat right now, without matter the scenario, lineup or rival. And today playing at home in the Champions League we can't expect any other result than a home win.

我认为皇马是最受欢迎的球队。

他们状态很好，踢得很好，有非常令人信服的表现。赢得迄今为止的7场比赛，包括欧洲超级杯，欧冠对阵凯尔特人(0:3)和所有联赛比赛。

是的，他们没有了本泽马，但球队已经表明他们有更多的选择。在没有他的情况下，他们在2场比赛中打进了7球(0:3 vs凯尔特人，4:1 vs马洛卡)，像维尼休斯或罗德里戈这样的球员在伟大的时刻。

安切洛蒂教练在联赛中进行了一些轮换，把莫德里奇、卡马文加或特chuameni等球员留在了板凳席上，以确保本场比赛的100%状态。

另一方面，莱比锡的状态真的很糟糕。他们在主场被非常糟糕的矿工队(1:4)摧毁，同时也以4:0输给了埃茵托赫特(他们在超级杯中被马德里以2:0击败)和3:5输给了拜仁慕尼黑(与马德里水平相似)。

他们在赛季初的糟糕表现迫使他们更换了教练，新教练马尔科·罗斯在周末对阵多特蒙德的比赛中(3:0)取得了一场大胜。

穆基尔在转会市场上的离开给巴黎圣日耳曼带来了很大的伤害，因为他是一个关键的后卫，而俱乐部没有签下任何好的替代者。此外，另一名关键后卫克洛斯特曼的脚踝严重受伤;所以这个赛季球队的防守非常薄弱。

主力球员丹尼·奥尔莫也因为长期受伤而缺席。

我认为莱比锡将尝试使用周末对阵多特蒙德时同样的战术(那场比赛3:0取胜)，用恩昆库和维尔纳这样的快速球员打一场反击比赛，在不制造高压力的情况下被压制。但皇马是一支非常清楚如何阻止反击的球队，当他们占据统治地位时，他们在进攻中有很多选择。

这里存在着巨大的质量差异。马德里状态很好，非常有竞争力，现在看起来不可能被击败，无论场景，阵容或对手。今天在欧冠主场比赛，我们只能期待一场主场胜利。
