Dortmund's coach was hit by explosions on its way to the Champions League quarter-final first leg against AS Monaco last Tuesday, with the Bundesliga side going on to lose the rescheduled fixture 3-2 a day later.
In all the games Dortmund played this season, Reus spent only 1,090 minutes on the pitch but was involved in 13 goals (seven goals, six assists).
Monaco fans unveiled a "You'll Never Walk Alone" banner, with the German team's anthem, which they share with Liverpool and Celtic, before kick-off.
For Monaco, the result means they reach the last four for the first time since their run to the 2003-04 final and the youth, vibrancy and pace they possess in abundance mean's Leonardo Jardim's men will be a threat to Real Madrid, Juventus or Atletico Madrid.
The hosts made the ideal start to the night and once again it was Kylian Mbappe - the scorer of two in the first leg - to the fore.
"We have taken France into the semifinals". Recent history has shown that Monaco has a resolute but not impenetrable defense, especially to a team that likes to attack from various angles like Dortmund does.
Mbappe is one of the rising stars of world football and the youngest player to score twice in the Champions League.
"Now we need to put in a good performance and I am convinced we can do it".
German midfielder Reus found the net at the start of the second half, but Monaco substitute Germain added a late third for Jardim's well-drilled outfit just moments after coming on. Everyone was prepared and in the bus, but we couldn't move for 16 or 17 minutes, " Tuchel said after after Dortmund were eliminated following a 6-3 aggregate defeat.
"If I have to choose, it's normal to prefer to win the Champions League, but maybe our chances of winning it are slimmer than winning the league. We pulled it back to 2-1 tonight and with more luck we could have forced extra time".
Bartra was there to support his teammates in Monaco but it was another hard night as their bus was delayed in leaving for the ground, held up by police for security reasons.
"We're more stable emotionally", said Tuchel ahead of Wednesday's return leg.
The kickoff was delayed by five minutes but Dortmund's concentration was again affected. I think the players are ready and are working well. "Our heads have to be focused on tomorrow's game, we're 90 minutes into the Champions League semi-finals but that's true for our opponents as well".
