"With their talisman out injured and their captain suspended, Brazil are in for a tough ride in their semi-final," Redknapp wrote in his column for the Daily Mail.
"They have been exciting to watch but mainly because they play off the cuff. Whereas Germany are a really solid team, Brazil sometimes play like a team of mavericks.
"I wonder if it could be Willian's time. That No 10 role is there for the taking and he or Oscar have to grab the chance. But with the star man missing, this could be a game too far for Brazil."
Brazil beat Germany in the 2002 World Cup final in the only previous tournament meeting between the teams.
