Lionel Messi's ability to both score and create goals means Germany boss Joachim Low would prefer him in his team ahead of Cristiano Ronaldo.
Ronaldo will hope to replicate the success Portugal enjoyed at Euro 2016 while Messi is seeking to atone for Argentina's defeat in the final at Brazil 2014.
"I would stick with Messi," Low told Bild.
"Cristiano Ronaldo is sensational, a very good professional, an incredible goalscoring machine for many years, but Messi is the most complete player I have seen.
"He is a great team player. He's provided 30 to 40 assists for the last 10 years as well as scoring around 50 goals.
"He's capable of leaving eight or nine players in his path and his goals always stay in your memory."
Low will attempt to lead Germany to back-to-back World Cup triumphs in Russia, a feat managed by only two other nations.
