Tuchel clarified that his selection policy is not a punishment but requires adherence to "non-negotiable standards" from all invited players.
England recently secured World Cup qualification with a 5-0 victory against Latvia, and Tuchel aims to maintain the squad's competitive edge and positive chemistry.
The manager confirmed he will contact players not in the current camp, including Bellingham, to explain their omission and encourage their return.
Tuchel expressed confidence that England will go to the World Cup with a strong team and spirit, listing Brazil, Argentina, Spain, France, and Portugal as potential favourites.
