Women's football could surpass the men's game, according to Jean-Michel Aulas.
Former Lyon president Aulas has been a major backer of women's football, with the French club having one of the most successful club sides in the female game.
During Aulas' time as president, Lyon's women's team have won a record 16 Division 1 Feminine titles and a record eight Women's Champions League crowns.
Speaking to Stats Perform at the inaugural European Club Association (ECA) Women's Football Summit in London, Aulas was bullish about the future of the women's game.
"In any case, whether you like it or not, it's inevitable. Tomorrow, women's soccer will be the equal of men's soccer, and maybe even better," he said.
"And it's an absolutely fantastic growth driver. You can see it when people try and I have this responsibility at the French Football Federation, to create a women's soccer that is overpowering.
"We don't want to let ourselves be overtaken by the English league or other leagues.
"So we're trying to create a dynamic and a self-generating model not only of belief, but also of economic results that will enable us to continue investing."
Aulas believes women's football is already more entertaining than men's.
"It's not marketing, it's not, it's concrete," he said when asked about athletic differences between the genders.
"It's that the effective playing time of women's soccer is far greater than the effective playing time of men's soccer. Why is that? Because we're not looking to gain time. We're not trying to betray the referee.
"And these figures show that, in athletic terms, there will soon be no difference. And then, in terms of state of mind, it's all in favour of women's soccer."
The 2023 Women's World Cup is set to be another huge driver in attracting a wider audience, and Aulas believes there are four clear favourites to succeed in Australia and New Zealand.
He explained: "I'm actually a double player in this World Cup since I'm responsible in France for leading the French team delegation. On a general level, I think that this World Cup will reflect what has already been the case in France, i.e. a very significant development in terms of spectators and television viewers.
"The competition is going to be even more competitive because the number of teams that can win and play a role today has increased.
"And then for the French team, of course, to try to go a little further than we have done in recent competitions with a new coach, Herve Renard, and also with a team that will be keen to reach the final rounds, to try to defend the image of France which, in the boys' game so far, has been very successful.
"For me, I see four teams who are perhaps the best of the lot. The United States, as always, obviously. And of course England, who have just won the European Cup with a lot of certainty and a lot of ambition.
"I can also see Brazil, who have some excellent players and are trying, as with the boys, to bring a highly technical style of women's soccer to the table. And then there's France.
"I see these four teams in the top places. There are always surprises, so it's simply a prediction."
Aulas also emphasised that the ECA presidents are firmly in favour of growing the women's game.
"The club presidents of the ECA, who are among the greatest club presidents of all European clubs, believe strongly in it," he said.
"So they're going to keep investing. And since we're in London, we can also see Chelsea investing heavily with American shareholders.
"That's what's going to enable us to strengthen women's soccer by developing the rules and bringing them closer together."
