The youngest coach in Champions League history, Julian Nagelsmann, has guided Hoffenheim to a 2-2 draw at Shakhtar Donetsk draw in their maiden match in the competition.
Nagelsmann, who turned 31 in July, was appointed by Hoffenheim in February 2016 at the age of 28 - the youngest coach in Bundeliga history - and qualified them for the Champions League for the first time by finishing third in the league last season.
He's 41 days younger than Belarusian Viktor Goncharenko was when he coached BATE Borisov against Real Madrid in the Champions League in 2008.
Nagelsmann had to wait just six minutes to see his team score a first Champions League goal with Florian Grillitsch on target.
Shakhtar responded with a solo effort from Ismaily in the 27th as the Brazilian charged down the left flank before leaving defender Havard Nordtveit sprawling as he cut inside and placed a shot inside the far post.
Nordtveit restored Hoffenheim's lead with a header in the 38th from a corner.
Andrej Kramaric came close to scoring a third in the second half.
However, Maycon's long-range shot in the 81st minute for Shakhtar meant the teams shared the points in Group F after a frantic finish in which Hoffenheim held off an onslaught from the hosts.
"You noticed at the end that the puff was missing a bit," Nagelsmann said.
"We could not defend so well any more."
