England travel to Australia on 5 July to prepare for their opening match of the tournament against Haiti on 22 July.
Following the Lionesses’ success at Euro 2022, they are seeking to win a first Women’s World Cup, having lost just once under manager Sarina Wiegman since her arrival in September 2021.
“You need to make sure you don’t forget to enjoy it because I know football can get tough at times and the pressure will be on,” said Russo.
“I play my best football when I’m having fun and enjoying myself. Obviously, the competition is going to be so high but if I just relax and not take a day out there for granted, then hopefully I can play my best football.”
Russo faces competition to start up front from Aston Villa’s Rachel Daly – who won the Women’s Super League Golden Boot this season – and Tottenham’s in-form goalscorer Bethany England.
“We are all competing. They are top, top players so to be able to play with them and train with them every day has been great,” said Russo.
“There is so much competition all over the pitch but, as a player, that’s exactly what you want in the squad.
“I’ve only been a number nine for two years really. I was out in America before that. There’s so much more for me to learn and I want to keep progressing. It’s going well but there’s lots more to come.”
