Marc Bartra "doing much better" after surgery

Minutes after the attacks the only question was whether the game could go through or not.

TRT World's Ben Said has more on how fans reacted.

Meanwhile Marco Reus has failed to recover from a thigh injury and will play no part in the Champions League quarter-final first leg against Monaco later tonight.

UEFA said security at all three of Wednesday's Champions League games was being reviewed.

Dortmund player Marc Bartra who was injured in the blasts.

Spokeswoman Frauke Koehler said investigators had found three letters near the scene, all with the same content suggesting a possible Islamist motive.

One of several claims of responsibility for the attack mentioned a demand for the withdrawal of German Tornado jets from Syria and the closure of the US Air Force's Ramstein air base in Germany. Their homes have been searched and one has been temporarily detained, she said.

German police later announced that they had arrested one suspect with what prosecutors described as links to "the Islamist spectrum", the Guardian reported.

"The team is in shock", Dortmund CEO Hans-Joachim Watzke said. "And of course we play for Marc Bartra, who wants to see his team win".

Germany has been on high alert since a series of jihadist attacks previous year, including the Berlin market assault.

Windows on the bus were broken in the attack, in which three explosions went off at 7:15 p.m. on Tuesday near the hotel where the team was staying.

A policeman, who was on a motorcycle escorting the team bus, suffered trauma from the noise of the blasts. According to the investigation, the explosive devices were apparently hidden in a fence and exploded just as the bus passed through the area.

"The bus then turned down the main street and there was a massive explosion". "After the bang, we all crouched down in the bus. We did not know if more would come".

The match has been postponed until Wednesday at 1845 (1645 GMT), which Barta will miss, and German daily Bild claim he will be sidelined for the rest of the season.

Dortmund fans used the hashtag "bed for away fans" to help Monaco supporters find accommodation after the match was postponed to Wednesday.

Bild put out a full-page advert in Dortmund's yellow and its BVB 09 logo, with the message: "You'll never walk alone". "I was proud of the solidarity shown by the red and white fans", said Mr Pascal Pedro, a Monaco fan.

"I have a bit more experience than my players and I told them not to worry so much about it, try not to think so much about it, it does not get better", Tuchel said.
