I didn't expect Corinthians -0.5 in par, my fair is -0.75 to 1.8.

I will give some reasons.

1st Reason: Difference in quality between the teams. Corinthians is one of the strongest Brazilian teams. This season they made a big bet for me on a mix of experienced players and promising youngsters. They chose a coach who has the full confidence of the players and the team is growing from game to game. The attack duo with Roger Guedes and Yuri Alberto is fearsome, they have both the level to play in the best teams in European football. Argentino Juniors is an average team in Argentina, Argentina is going through a serious economic crisis and this is reflected in the technical quality of the teams. The best players are leaving the country, including for Brazilian teams. The gap in South America is getting bigger.

2nd Reason: Must win. The next two trips for Corinthians will be to Argentina against the same Argentino Juniors and to Ecuador against Independiente Dell Valle, where there is altitude. So winning at home games is a must.

3rd Reason: Home factor. Corinthians probably have the strongest home field in Brazil. It is very difficult for opponents to play there. The fans are known as "the crazy bunch". They never whistle the team during the 90 minutes, even if things are difficult they support the team during the 90 minutes. Always singing, that gives the players a lot of strength, who even when the games are difficult, find the goal rocked by the fans.

我没想到科林蒂安的平均水平是-0.5，我的平均水平是-0.75到1.8。

我会给出一些理由。

第一个原因:团队之间的质量差异。科林蒂安是巴西最强的球队之一。这个赛季他们在我身上下了很大的赌注，把有经验的球员和有前途的年轻人组合在一起。他们选择了一位对球员充满信心的教练，球队也在一场接一场地成长。罗杰·格德斯和尤里·阿尔贝托组成的进攻组合是可怕的，他们都有能力在欧洲最好的球队踢球。阿根廷青年队在阿根廷是一支普通的球队，阿根廷正在经历严重的经济危机，这反映在球队的技术质量上。最好的球员正在离开这个国家，包括巴西球队。南美的差距越来越大。

第二个理由:一定要赢。接下来的两场比赛，科林蒂安将是阿根廷对阵同一支阿根廷青年队，以及厄瓜多尔对阵海拔较高的戴尔瓦莱独立队。所以赢得主场比赛是必须的。

第三个原因:家庭因素。科林蒂安可能拥有巴西最强的主场。对手很难在那里比赛。这些球迷被称为“疯狂的一群人”。他们从不在90分钟内吹口哨，即使情况很困难，他们也会在90分钟内支持球队。总是唱歌，这给了球员很多力量，即使在比赛很困难的时候，他们也会发现进球被球迷震动。
