The Hertha Berlin team bus was reportedly shot at by a motorcyclist carrying a firearm the day before the club's German Cup clash against Bielefeld.
The driver, who did not have any passengers at the time, was travelling from the Bundesliga side's hotel to a train station to pick up the team when the attack occurred on Sunday.
A bullet smashed through the windscreen of the coach, leaving a hole close to the level of the driver's head.
"It's crazy," AFP quotes Hertha manager Michael Preetz as saying. "We consider this as attempted murder. Our driver was going from the hotel to the train station at Bielefeld to collect the team. An unidentified person on a motorbike fired at the bus."
Preetz added that the "type of firearm used has not yet been determined", but police are investigating the incident.
