They are under immense pressure as they prepare for long-time rivals Argentina, who are top with 12 points.
“I hope we play well and the fans can create a great atmosphere and play with the team,” Diniz said.
“We are ready to play a team that is one of the best, if not the best (team in the world). And they have been there for a while, not just because they have won the World Cup.
“They have players from the biggest leagues, who are in the headlines. And there is Messi… This is a team that has been playing well for a long time, has a winning streak and has kept its base.
“We accept that and we’re going to prepare to do our best against a great opponent.”
