Brazil goalkeeper Alisson says there are no room for errors in Wednesday's Copa America semi-final against Lionel Messi and Argentina.
Alisson managed to stop Barcelona star Messi in the Champions League for the past two seasons, with Liverpool and Roma.
And he knows Selecao must be on point to make it to the final.
"I have confidence in my team, in my work, in the conviction that we are going to make a great game, we have to be prepared for everything," Alisson told a news conference.
"Roma and Liverpool were both very different. Fortunately they were two happy stories for my side.
"I was on two teams that played collectively. Our team has played like this, as a team, with a relationship. I have now lived two important experiences.
"But in a game like this there is no room for error against Argentina, everyone has to give their best."
