The 25-year-old from Bonn has been coached by O'Sullivan since June 2021.
O'Sullivan was in the RTÉ studio where she gave her reaction to 'Koko's' superb victory.
"We know Koko's super talented and she's won a bronze medal at the World Championships but she hasn't run anything like that in a long time," a delighted O'Sullivan said.
"I think it was (the secret) being in Munich with the home crowd behind her.
"She hasn't finished so strong in a race all year.
"You could see the emotion at the end, how much it meant to her."
Derval O'Rourke who was also on the panel paid tribute to her colleague.
"What an effort from coach Sonia.
"She was sitting here as cool as a cucumber not a bother on her.
"That's the moment of a career; gold and European champion in your home country, in front of all those people screaming your name. She is loved there."

'Thank you Sonia so much, I send you lots of love... I know you won the title in Munich as well!'

Ireland's Roisin Flanagan from Tyrone finished in a respectable 14th, just seven seconds outside the PB she set at the Commonwealth Games less than two weeks ago.
Earlier in the evening Andrew Coscoran finished 9th in the final of the 1500m.
The Balbriggan man finished in a time of 3:39.91, some way short of his PB of 3:35.66.
Norwegian star Jacob Ingebrigtsen took victory leading the field from start to finish.
Ingebrigtsen secured the 1500m/5000m double in comfortable fashion.
