World Rugby chief executive Brett Gosper has hinted that the 2023 Rugby World Cup could well be expanded in order to include more nations.
He stressed the proposed move would not lead to the tournament losing its competitiveness, but would "promote the sport in their (other) countries".
England host this year's fast-approaching tournament before Japan will be the setting for the 2019 event, with 20 teams involved in both of the spectacles.
"As the sport grows and we conquer new markets the discussion is about looking towards expanding, rather than contracting," Gosper told a Sport Industry Group Breakfast Club gathering in London on Tuesday.
He highlighted Germany as being one country that could benefit from the expansion, which of course would bring greater financial gains through television deals and sponsorship. Gosper went on to say that he was encouraged with the progress being made in USA, India, China and Mexico.
"Rugby is the fastest growing team sport in the USA," he said.
"We are in very good shape, in all formats, around the world."
