The 29-year-old Özil announced his international retirement in July after Germany crashed out of the World Cup group stage in Russia. He said he had faced “racism and disrespect” because of his Turkish roots.
“Basically, Mesut is a deserved international, and as a player he deserved a better departure,” Kroos told Bild newspaper in an interview published on Thursday. “But the way he resigned was not in order.”
Özil was a key member of Germany’s World Cup-winning side in 2014 and was voted by fans as the team’s player of the year five times since 2011.
But the creative midfielder faced a barrage of criticism at home for having his photograph taken with Turkish President Recep Tayyip Erdoğan in May and for his performances at the World Cup in Russia.
In his resignation statement last month, Özil also accused the German Football Association of failing to back him in the row over the photo.
German fans jeered him and İlkay Gündoğan, a team mate also of Turkish descent who posed with Erdoğan as well, during World Cup warmup games in May.
“The parts in his statement that are rightly addressed are unfortunately overshadowed by the significantly higher amount of nonsense,” Kroos said. “I think he knows very well that racism within the national team and the DFB does not exist.”
Germany failed to qualify from the World Cup group stage in Russia, making their earliest exit from the tournament in 80 years, and Özil was one of the scapegoats for their unsuccessful title defence.
“In the eyes of (German FA President Reinhard) Grindel and his supporters I am German when we win, but I am an immigrant when we lose,” Özil wrote in his statement.
The 28-year-old Kroos, who has won the last three Champions League titles with Real Madrid, said he had no plans to follow Özil into international retirement after their World Cup flop.
“I will continue towards Euro 2020 and have set myself the goal of being far more successful there than in the recent past,” Kroos said.
“I had a good talk with (national team coach) Joachim Löw. “We will find solutions together so that I can get a break here and there. For me that’s the only way, and I am thankful for Jogi’s understanding.”
