The Brazil international, who is suspended for Wednesday's Champions League clash with reported suitors Real Madrid, shrugged off the rough treatment to score a spectacular overhead kick winner in a 1-0 victory over Strasbourg on Saturday.
Neymar said afterwards that all matches would be "away games" for him now, having irked fans with his desire to leave the club in the last transfer window.
Tuchel reiterated there is no issue between him and the former Barcelona star, but can see why fans may choose not to forgive Neymar for his actions.
"He did not want to be here. He tried everything that was in his power [to leave the club]," Tuchel told DAZN.
"That did not help make him popular. You could feel that and I can understand it, if the crowd are angry, even permanently.
"Nevertheless, there is also a side between me as a coach and him as a player. There was never a break or a discrepancy. That's why it was very easy for me to let him play.
"He has always trained professionally. I feel that the decision was a relief to him, even though it fell against his wish.
"Then the concentration and reflection on the task automatically occurs. As an athlete you will not have much else left. You have to give gas. He is hungry and a competitive guy who always wants to win.
"He has to withstand it now, that's the reality. He has to go through, we have to go through all in the home games a bit. The best thing is to come to terms with it."
