Jerome Boateng and Toni Kroos have praised Germany head coach Joachim Low as a "top-level coach" and "good person."
Low was appointed Germany head coach in 2006 and steered the team to victories at the 2014 FIFA World Cup in Brazil and the 2017 FIFA Confederations Cup.
"I know Low since 2010, and he's growing as a coach, he's developing constantly, which is normal," said Boating.
"You should always be open to anything new if you're heading the national team for so many years. He became stronger in terms of his attitude to the process, in terms of his demands. He is just a top-level coach."
Kroos added that Low was "a good coach and a good person."
"He grows with every tournament. He can give players a confidence boost, it's very important to be able to do so," Kroos said.
Reigning champions Germany will face Mexico, Sweden and South Korea in Group F.
