Bellingham was left out of this past week's internationals, which saw England secure World Cup qualification.
Asked if he would speak to Bellingham before naming his squad for the next international break, Tuchel said: “I guess so. Why not? Of course, he's an important player, he's a big player.
“I will speak to a lot of players, also to the guys that will get a text from me who were not in camp. Because these guys who are now here, they have the reward, and they feel the reward. And it's now necessary also that I stay in touch with the other guys.
“No one has done anything wrong. It's not a punishment or whatever. And I feel when I text them and I speak to them, that everyone is eager to come back. And this is how it has to be. And I trust in more players than are here.
“We always speak about the same names, but we have Conor Gallagher, we have Trevoh Chalobah, and we have Cole Palmer injured. So there are a lot of guys out there who would deserve to be with them, and who are hungry and determined to be with us. It has to be like that.
“But I don't doubt, if we invite them, then we are sure that they will buy in. Otherwise, we will not invite them. Why would we? This is a non-negotiable.”
