We will have to take advantage of Flamengo's -0.75, I'll give some reasons.

1st Reason: Difference in the quality of the teams. Flamengo is the best team in South America in terms of quality, they have the best players in Brazil and now they have signed A. Pereira from Manchester United and Kenedy from Chelsea. This demonstrates how they are above the opposing teams. Grêmio on the other hand is going through a moment of reformulation and has some players who were discredited.

2nd Reason: Coach. R. Gaucho was Grêmio's coach from 2016 to 2021. He knows the team like no one else, he knows their strengths and weaknesses, he knows the players and how they play. He will exploit all the weaknesses of the team, he will be a determining factor here.

3rd Reason: Must win, focus on competition. R. Gaucho is a coach who prefers cups to championships. That's why the Brazil Cup and Libertadores are the Flamengo's main objectives. He rested some players in the last game of the championship and with that he demonstrated what his main objective is. While Grêmio is having a season to forget and is at risk of relegation on championship. So the focus is all on the championship and Felipão (coach) has already come to say that what matters is to maintain the team in Serie A.

Without fans the home factor is no longer so strong and Flamengo is much better technically and tactically and wants to win this game at all costs.

我们将不得不利用弗拉门戈的-0.75，我将给出一些理由。

第一个原因:团队的质量不同。就实力而言，弗拉门戈是南美最好的球队，他们拥有巴西最好的球员，现在他们已经签下了曼联的佩雷拉和切尔西的肯尼迪。这表明他们是如何凌驾于对手之上的。另一方面，Grêmio正在经历一段时间的重新规划，有一些球员是不可信的。

原因2:教练。R. Gaucho在2016年至2021年期间担任Grêmio的教练。他比任何人都了解这支球队，他知道他们的长处和短处，他了解球员和他们的打球方式。他会利用球队的所有弱点，在这里他将是决定性的因素。

第三个理由:一定要赢，注重竞争。R. Gaucho是一个喜欢杯子胜过冠军的教练。这就是为什么巴西杯和解放者队是弗拉门戈队的主要目标。在锦标赛的最后一场比赛中，他让一些球员休息，并以此证明了他的主要目标是什么。而Grêmio还有一个赛季要忘记，还有降级的危险。所以所有的焦点都集中在冠军上，Felipão(教练)已经开始说，重要的是保持球队在巴甲。

没有了球迷，主场就不再那么强大了，弗拉门戈在技术和战术上都做得更好，他想要不惜一切代价赢得这场比赛。
