Germany boss Joachim Low has made it clear that he will be watching Cristiano Ronaldo closely in their opening World Cup clash with Portugal.
Die Mannschaft take on the Portuguese in Salvador on Monday in their Group G opener and Low says he will try to use key defender Jerome Boateng to hold down the Real Madrid star.
"It does play a role who can keep Ronaldo in check, and Jerome Boateng has done that in the past," Low said.
"So too has (Philipp) Lahm so together they will deal with him.
"You cannot let him out of your sight, literally. You've always got to ask 'what's Ronaldo doing, where is Ronaldo'.
"Ronaldo and Nani seem to be drifting into no-man's land, then the ball is suddenly there at their feet and they are ready to attack you."
Low added: "When Germany play Portugal, there is no favourite."
