I keep wondering how these Vasco guys managed to score 6 goals against Santos

In this game against Juventude, for example, Vasco had 77% possession, but they couldn't even score a single goal. This often made me wonder how they managed to score 6 goals against Santos. Juventude didn't have a very strong defense, but Vasco still didn't score a single goal. Two interesting things are worth mentioning:
1 - In the last 5 games, Juventude has conceded a goal in every game; in some games, they even conceded 3 goals.
2 - Juventude lost to Santos, in a game in which they conceded 3 goals.
So, Santos scores 3 goals and beats Juventude, then concedes 6 goals against Vasco, who wins and scores 2 goals against Juventude. Honestly, the Brazilian league is very unpredictable.
Juventude football team won the last match which they played against Vasco da Gama football team and that team did 2 goals in this match and opponent team could not do any goal in this match. Nenê was a person who did first goal of the match and he did this goal at 3 minutes and that goal was at penalty. Vasco da Gama team stats was excellent in this match as their shots were 14 in this match and only 2 shots were on target. The possession percentage of that team was 77 percent in this match and passes of that team were also more in number and these were 847 . The pass accuracy of that team was brilliant in this match which was 94 percent but that team could not do any goal in this match and that team lost the match in the end.
