Hope Solo believes hosts France pose the biggest challenge to the United States' Women's World Cup defence.
Solo helped the USWNT to glory in Canada four years ago and was named the leading goalkeeper in the tournament for the past two editions.
The 37-year-old will look on as a spectator this time around, following the end of her international career in 2016, and feels Les Bleues could come to delight the home crowd when the World Cup kicks off next month, despite them being placed fourth – behind the States, Germany and England – in FIFA's official rankings.
