"I think India has a great potential as a table tennis nation. There are many players who have good energy and there are coaches who are interested to educate themselves about the game. The coming 10-15 years it will be very interesting for Indian table tennis," Karlsson told reporters at the Bombay University stadium.
Karlsson, who won four world men's team titles with Sweden and one men's doubles crown between 1989 and 2000, is in the city to conduct a four-day training camp organised by the Mumbai City District Table Tennis Association.
The Swede has been training men's national champion and India no 1 Soumyajit Ghosh for the last two years and said the Siliguri player can break into the top 100 very soon, though he needs to improve his physical fitness.
"I told him we have to work on physical fitness. He was ready to work. It was a little bit painful for him and he has done a great job but still, he has to do more work on physical fitness to take the next step," the Swede said.
