Thomas Tuchel says Jude Bellingham must "accept" his decision making after the England midfielder showed his frustration at being substituted during the 2-0 win against Albania.
Harry Kane's second-half double secured a 2-0 victory in Tirana that saw the Euro 2024 runners-up complete a flawless Group K campaign with an eighth win and eighth clean sheet.
Bellingham was among seven changes to Thursday's win against Serbia and was brought off six minutes from the end of his first England start since June.
The 22-year-old put his arms in the air in frustration just after Kane headed the second goal in, having seen Morgan Rogers waiting to replace him on the touchline.
When asked about Bellingham's reaction to the substitution, Tuchel said: "That is a decision and he has to accept the decision.
"His friend is waiting on the sidelines. Accept it, respect it and keep on going."
Tuchel was then asked if the reaction goes against the attitude he is trying to instil in his squad ahead of the World Cup next summer, to which he added: "I didn't see it that way.
"I will need to review it and I saw he was not happy. I do not want to make it bigger at the moment than it is. Players like Jude are so competitive, they will never like it.
"My word stands; it is about standards and a level It is a commitment and respect to each other. We will not change our decision because someone waves their arms."
