Kurtz, who assisted countryman Gerhard Rach as coach of the Indian team in the 2004 Athens Olympics where the team finished seventh, reminisces his short stint with India and said a professional approach is key to any country's success in modern day hockey.
"Indian hockey is more professional now. It is making a big difference. There is a totally different culture in Asia.
Earlier, there was no professionalism in teams like India and Pakistan which I believe is a reason behind their fall in world hockey," Kurtz told PTI in an interview on the sidelines of the ninth Asia Cup here.
"If you look at teams like Australia, Germany you will get an idea how professionally they work. The daily routine of these teams, the fitness level of their players...
"Indian hockey is slowly becoming more professional. They have hired specialised people for every aspect of the game. In Hockey India League, India now has the world's biggest and most expensive hockey league," said Kurtz, who is here as the coach of Oman.
The former German striker said Indian hockey's decision to invest on youth paid rich dividends.
"In the last 3-4 years India has focussed on the youth and now this is getting them results. I always love to see India playing good hockey. Individually the Indian players are very good," said Kurtz, who was a member of Germany's gold medal winning team in 1992 Barcelona Olympics.
