Mark Sampson’s squad are in Chongqing for the CFA International Women’s Football Tournament, where they will take on the host nation and Australia over the next seven days.
And Jagielka, who led his country to victory over Lithuania earlier this month, believes the Lionesses’ success at this summer’s World Cup will only serve to get more girls interested in putting on a pair of boots.
He said: "I’ve seen how English women’s football has been doing and there has been a lot more investment into things.
"Everton have had success and won The FA Women’s Cup a few years back and some of those players have now gone on to other teams, like Manchester City, who have a purpose-built stadium. There’s a lot of money going into it.
"Watching the games at the World Cup over in Canada was exciting," he continued.
"It’s always good to see an England team do well, whether that’s football, cricket or rugby, being a proud Englishman. But the women’s football was fantastic to watch and I was proud as punch that they did really well.
"If that paves the way for more girls to take up football then it’s brilliant."
One girl who is keen on a kickabout is Jagielka’s daughter, who watched Sampson's side in action this summer, and enjoys taking on her dad at home.
Jagielka said: "She’s into gymnastics but she comes out and plays with me and my son when we play in the back garden.

"She doesn’t play for a team or anything, but she joins in with us whenever she can.
He added: "She enjoys playing which is the main thing. I want both my kids to play as many sports as they can."
