The Brazilian shot stopper has barely been tested in the three games he has played for his side in the tournament.
Alisson and his teammates defeated South Korea 4-1 in the round of 16 to reach the quarter finals.
However, Schmeichel believes that Alisson always has a mistake in him.
“I like the way Ederson plays. I like his style. I like how good he is with his feet and people question him. I like Ederson. I like the way he plays. When people say 'yeah, he's good with his feet'," Schmeichel told beIN Sport.
"He's very, very good as a goalkeeper as well. He makes big saves. Crucial saves. He fits into that Manchester City team so well. Therefore, I can't say I prefer one to the other because I don't know how he (Ederson) would fit into the Brazil team.
"I think the goalkeeper that you pick for your team has to fit into the way you play. If you can point anything towards Alisson. Everything (he has) is the traditional goalkeeping saving. One v One, all of that. Coming for crosses, he's very good.
"But there is always a mistake. It's like he is overestimating the time on the ball he has. There is always something where you are a little bit worried. I never have that with the other one."
