The Crystal Palace player was blocked from facing his parent club in the FA Cup semi-finals by the Blues.
The Blues turned down the request because of the terms of the loan deal.
He made his senior England debut in November, after impressing since joining Palace.
Tuchel said that the decision was the right one.
He said that he had the chance to speak to Conor, and that he could also see his frustration.
We met after the international break in a restaurant and had a chat and the subject came up. I apologized.
I know how competitive he is and I like him a lot, so it was a pleasure to have him here in pre-season.
The rules were clear when we made the loan. I understand the disappointment of Conor, but these were the rules when we made the loan and we don't want to suffer from them.
With eight-time winners Chelsea trying to reach the showpiece final for the third year in a row, they face Palace at Wembley on Sunday.
