Yesterday Flamengo had a very easy victory in the game against Internacional

I consider it an easy victory because Internacional didn't pose much danger to Flamengo. It was a game in which Flamengo was under less pressure and could have scored more than two goals if they had better leverage on their opportunities. In the first half alone, they could have scored at least two goals, and in the second half, they could also have scored at least two goals.
In total, Flamengo would have scored four goals in that game. Unfortunately, they aren't very effective in attack. They were lucky that their opponent was also weak in attack and weak in defense. That's why we won, but if we play against strong opponents, I believe our chances of losing will be greater.
