Speaking to the Metro, Vieira said, "You need two around him to give him more protection but I don’t know if Rudiger is the type of player that you can count on him, he’s not the smartest one.
"Sometimes he makes a poor decision that gives his teammates a big big problems.
"We saw the goals that Germany concede against France he can do silly things the bite on Pogba he’s somebody that can lose his head in any moment during a game.
"I think Hummels is not the quickest one but he’s really smart and uses his brain to try to defend well but it’s going to be tough at this level for him."
Following Germany's impressive win over Portugal and indeed, being key to Chelsea's Champions League success, Rudiger will not be inclined to listen to criticism like this.
The Chelsea man has impressed in terms of pressuring opponents smartly, ranking in the top 10 for Chelsea in both attempted and successful pressures, meaning he plays excellent team football.
