Spanish defender Marc Bartra suffered injuries in the wrist and arm and underwent an operation Tuesday night.
Tuesday's first-leg match was postponed and rescheduled for Wednesday, with Monaco winning 3-2.
"What will stay in history is not the result but what happened last night".
"The situation is absurd", Tuchel told a news conference. I doubt they would have had any preparation or rest and to suddenly expect them to perform would have been a step too far.
"They [UEFA] have to understand that we are not animals".
Dortmund defender Sokratis Papastathopoulos said he felt he had been treated like an "animal and not a person". "We know the quality of Dortmund and also the support of their supporters, the atmosphere".
After the break, Dortmund roused themselves and got one back, courtesy of French winger Ousmane Dembele who fired home after an initial flick from Pierre-Emerick Aubameyang's.
"From what I heard from team sources, many players didn't want to play today". I was waiting like the rest of the world for more information.
Dortmund fell further behind when Sven Bender, with perhaps an eye on Radamel Falcao lurking behind, headed Andrea Raggi's superb cross into his own net.
"Players crave normality. I'm not sure how long it would take (to recover psychologically) but credit to them for playing. There is so much more than football in this world and last night we felt it". But at the same time, we know that we are only half way.
As the players came out, the home team donned yellow training shirts with a picture of the injured Bartra as a rapturous cheer from the stands went up to show their united front.
"There were no other alternatives than to play".
"This is certainly a hard situation for the team which, I think, has not experienced such a situation before", Rauball said.
Dortmund coach Thomas Tuchel said Bartra will be out for about four weeks. You try to do everything the same way as we usually do. "You're the best athlete if you're not anxious".
Dortmund coach Thomas Tuchel angrily accused UEFA of treating the bomb attack as if a "beer can" had been thrown and claimed they were informed by text message that they would have to play their Champions League game. But all of them wanted to play.
Prosecutors say Abdul Beset A., whose surname wasn't provided due to German privacy laws, remained in contact with members of IS after arriving in Germany in early 2016.
Federal prosecutors in Germany said yesterday that they were investigating a possible "terrorist link" to the attack.
An "Islamist" suspect has since been arrested for the attack, which left Dortmund defender and Spanish global Marc Bartra requiring surgery.
"The investigation has not found evidence that the suspect took part in the attack", the prosecutors office said in a brief statement.
