Joachim Low's decision to cut the winger from the final squad for the tournament in Russia after an excellent season at club level was questioned by the likes of Germany legend Michael Ballack and City team-mate Kevin De Bruyne.
The 22-year-old, who featured in six of Germany's previous seven games before he was dropped, pledged to "bounce back" from the disappointment, and Draxler has faith that his friend will be fine.
"That he had to go home was also a surprise for us," Draxler told reporters. "He has had a very, very strong season in England.
"I've known Leroy for a long time, we're friends, so I'm especially sorry for him. But we all have to accept the decision, the national coach will have had his reasons.
"Leroy is certainly not as relaxed as he always is. He will be very disappointed, but it will not throw him off track."
After captaining Germany to Confederations Cup success in 2017, Draxler will play a key role for the world champions this year and he is happy with his standing in the national team.
"I have been here permanently since I was 18 years old. I know the processes and I've matured as a player," the 24-year-old. "At some point there will be a change, and then there are players who have to grow into new roles. It would be desirable for me to take a leading role. But that is of course only done by performing at club level and for the national team.
"You don't stand up and say: As of today, I'm a leader. It's a process. But it's already my goal to accomplish that."
"Professionally, everyone is convinced of him. I have no prejudices. It may have been said that he is a difficult guy, but he has his personality and I am really looking forward to meeting him. It's certainly an advantage if you can communicate in German. I'm very much looking forward to Thomas Tuchel and I am pleased that he is coming to Paris."
