I believe that São Paulo goes at least to -0.75 and I am not surprised by the -1. So we have a big bet here at -0.5. I will give some reasons.

1st Reason: Big difference in the quality of the teams. The Peruvian teams in terms of quality together with those from Bolivia are the weakest in South America. For example, Grêmo in a previous stage won 6-1 against Ayacucho and then playing away with the reserves and youth players and still won 1-2. This demonstrates the difference in quality between the Brazilian and Peruvian teams.

2nd Reason: The game will not be at altitude, the Bolivian and Peruvian teams when they are from cities like Cusco, Juliaca or La Paz can be very strong at home. But the Sp. Cristal is from Lima where there is no altitude. In addition, the game, instead of being at the skimpy stadium of Sp. Cristal, will be at Estadio Nacional de Lima, it is a very good stadium, with a good field and that favors the Brazilian team. It is the stadium where was Libertadores 2019 final. This game without fans, takes away a lot of the home factor.

3rd reason: Shape of São Paulo. They hired H. Crespo to coach won Sudamerica last season at Defensa y Justicia. He is very good and this is having an effect, for me they are the team playing the best football in Brazil at the moment.

我相信圣保罗至少会跌至-0.75，我对-1都不感到意外。所以我们在让0.5有很好的机会，我会给出一些理由。

第一个原因:两支球队的质量差别很大。秘鲁队和玻利维亚队在质量上是南美洲最弱的。例如，Grêmo在上一阶段以6-1击败阿亚库乔，然后与预备队和青年球员比赛，仍然以1-2获胜。这表明了巴西和秘鲁球队在质量上的不同。

第二个理由:比赛不会在高海拔上进行，来自库斯科、茱莉亚卡或拉巴斯等城市的玻利维亚和秘鲁球队可以在主场非常强大。但水晶香槟来自利马，那里没有高海拔。此外，这场比赛将在利马国家体育场举行，而不是在狭窄的水晶球场，这是一个非常好的球场，有一个很好的场地，这对巴西队有利。这是解放者队2019年决赛的场地。这场没有球迷的比赛，剥夺了很多主场因素。

第三个原因:圣保罗的状态。他们雇佣了克雷斯波担任上赛季在防守正义队夺得南美冠军的教练。他非常出色，这对我有影响，对我来说，他们是目前巴西踢得最好的球队。
