World Cup winner Megan Rapinoe has said she believes America’s National Women’s Soccer League needs more investment.

Earlier this month, the NWSL announced a near-20 per cent increase in the salary cap in addition to extra funding to allow clubs to invest in players above the maximum salary.

However, Rapinoe has criticised the move as the funds cannot be used to pay players who play for the US or Canadian national teams.

She said: “We need to sit down and have more substantive conversations about what that looks like.

“It’s going to be a necessary step before the NWSL gets going next year.” Rapinoe told Reuters.

Attendances at the NWSL increased this past season to an average of 7,337 fans per game, but Rapinoe isn’t happy about the slow progress and said when she retires she’d love to make an impact by buying a team of her own.

The 34-year-old added: “More resources need to be put into the front office of the NWSL.

“I’d be a great owner. I want to own one of these teams. If the only thing that’s said about us is how inspiring we are to little girls, then our marketing plan is a complete and utter failure. Make me want to go to the game.”
