"He proceeded in stages," Urban said of Thomas. "First he outed himself to his wife. Then he told his coach and then two players. After each step he received positive feedback.
"He was told by everyone that he was still the same person. This enabled him to increase his self-esteem until it was big enough to go public. He then got exceptionally positive feedback."
An openly gay football star would be a turning point not just for the sport, declares Urban, but also for society as a whole.
Football, he suggests, stretches into areas where attitudes towards homosexuality have so far proved difficult to change.
"Football is the only way to tackle this topic comprehensively," he said. "Very many people are geared towards football role models on television.
"If world soccer stars accepted their homosexuality, young people would question having to be so rough and macho.
"The result would be a social change that goes far beyond football."
Urban is now comfortable with his sexuality, but he is not impervious to the homophobic barbs he often overhears in general conversation.
"'F****, f****t', any negative way of calling someone gay," replies Urban when asked which insults he hears. "I was constantly affected by insults. Although it is not said to me directly it concerns me, even today."
"But today, with more self-esteem and confidence, I look at homophobia from the perspective of a personal coaches and diversity consultant. Sometimes I have to laugh about it too, because it's stupid and ridiculous."
Self-esteem and confidence have helped Urban to heal the wounds inflicted by his first love, football.
He is once more besotted with the sport, playing with and against gay-friendly teams from across the globe.
It might not be playing at a World Cup with the German national team, but Urban is now back on the pitch, this time with his head held high.
"I really wanted to play for the men's national team," reflected Urban. "It makes me happy to have made something out of my experiences.
"For years I could never play football in the stadium. I saw the grass and could not stand being a spectator rather than being down playing on the pitch. I had regrets, I was sad and angry.
"After I came out I was so much more confident. I played football at university, in a team consisting predominantly of gay footballers against other gay teams from Paris, London or New York and Washington.
"Today, I play at a club in Hamburg, accepted by everyone and my teammates are proud of me, I think. It is a great experience to play football and to feel free, pure happiness.
"There are certainly more boring lives than mine."
