I did preview the first leg, picked an easy home with a handicap and it came home by the 2-0 scoreline, but in fact the difference on the pitch was far bigger than that, which is why I still choose to take Real Madrid win even if they can afford to lose this game by a single goal to qualify.

Chelsea probable lineup:

Havertz has been mentioned a doubt, but defensively Chelsea coach has to make some changes as Chillwell is suspended and Koulibaly injured.

In the local league Chelsea are 5 matches without a win, and their latest performance at home was a disaster as the visiting Brighton side humiliated them badly on the pitch. The explanation after the game was " we did not know they were this good."

Well, they know how good Real Madrid is, and the current form of Real is very convincing:

the only match where the opponent was better than Real was Barcelona away a month ago, but in the latest games they have shown attacking - and goal scoring - skills as they have created masses of xG, they could had won over Cadiz easily by 5 goals according to xG-data, and they scored 2 against Villarreal, 6 against Valladolid! There was a hat trick for Benzema against Barcelona in the cup semifinal, as well as in the Valladolid match. He is closing to his best form, and that is bad news for Chelsea as with Vinicius they are unstoppable together!

Real likely starting lineup:

The big doubt is - or is it really - over Vinicius who rested the match against Cadiz. He was not needed, he is needed now. With Camavinga they will dominate the left wing from the start, cause faults, free-kicks, cards, and create goals.

Good luck!

我确实预测了首回合比赛，选择了一个有障碍的轻松主场，并以2-0的比分回家，但实际上球场上的差距远远大于这一点，这就是为什么我仍然选择让皇马获胜，即使他们可以在这场比赛中输掉一球以获得出线资格。

哈弗茨的出场受到质疑，但是切尔西主教练不得不在防守端做出一些改变，因为齐维尔停赛，库利巴利受伤。

在当地联赛中，切尔西已经5场比赛未尝胜绩，他们最近在主场的表现简直是一场灾难，因为做客的布莱顿队在球场上让他们颜面尽失。赛后的解释是“我们不知道他们这么厉害。”

嗯，他们知道皇马有多好，皇马现在的状态很有说服力:

唯一一场对手比皇马强的比赛是一个月前的巴塞罗那，但在最近的比赛中，他们展示了进攻和进球的技巧，因为他们创造了大量的xG，根据xG数据，他们本可以轻松地以5球击败加的斯，他们对比利亚雷亚尔进了2球，对巴拉多利德进了6球!本泽马在半决赛对阵巴萨的比赛中上演了帽子戏法，在巴利亚多利德的比赛中也是如此。他正在接近他的最佳状态，这对切尔西来说是个坏消息，因为他们和维尼修斯在一起是不可阻挡的!

最大的疑问是——或者真的是——维尼修斯在对阵加的斯的比赛中休息。以前不需要他，现在需要他。有了卡马文加，他们将从一开始就统治左翼，制造失误，任意球，卡牌，创造进球。
