"It will not be easy to get it out of our mind. In such a crisis situation, all of Borussia Dortmund will pull together. I think the team will feel it tomorrow."
Watzke explained what happened from the point of view of the Dortmund players, with the explosions occurring in theHochsten area of the city.
"There was an explosive strike in the immediate vicinity of the hotel exit," he said.
"When the squad moved from the hotel parking lot to Wittbrauckerstrasse, three explosive devices were triggered there.
"Marc Bartra has been taken to the hospital. He hurt himself on the hand.

Dortmund presidentReinhard Rauball backed the club's players to deliver a positive display against Monaco despite Tuesday's explosion.
"Of course this is an extremely difficult situation for the players," Rauball told Sky. "But they are professionals and I am convinced that they will put that away and will bring their performance tomorrow.
"It would be a bad thing for those who did that to succeed, because the team is influenced in some way."
