Agyemang was a headline inclusion in Wiegman’s Euro 2025 squad, having made only one senior appearance before the tournament.
She made headlines on her debut in April, scoring just 41 seconds after being introduced against Belgium.
Asked if Agyemang could be a “wildcard” off the bench after naming her in the 23-player squad, Wiegman said: “Yeah I think so, I think so. We will see what she can bring.
“I have seen her in training sessions and what she did in Belgium – she can bring something different. I hope she can show that.”
It’s safe to say Agyemang showed Wiegman what she can do.
Her goal against Italy was her second in Switzerland, making her the first teenager to net twice at a Women’s Euros since Cecilie Pedersen for Norway in 2009.
The 19-year-old says she doesn’t know how she keeps saving England when they need it most.
“I don’t know,” she said after the game in Geneva. “It’s by the grace of God. We are doing wonders as a team and I am so proud that I can say I’m a part of this team.”
England captain Leah Williamson, who was replaced by her Arsenal team-mate Agyemang in the 85th minute said: “She feels inevitable right now.
“She is quality. What she brings, she is a nightmare to play against. I’m glad she is my teammate for club and country. She deserves her flowers, I hope she gets them, I hope she enjoys tonight and I hope she is ready to go at the weekend.”
BBC Sport pundit Nedum Onuoha, who backed Agyemang to have a breakthrough tournament, added: “She’s 19 years old in a European Championship semi-final and she played like she had been there tonnes of times like some of her team-mates.
“She is an absolute star.”
Agyemang almost scored a second against Italy when she lobbed the goalkeeper and hit the crossbar minutes before Kelly’s penalty.
“She nearly got the winner,” England’s record goalscorer Ellen White said.
“I think she is just a special, special player, a special human being. She plays beyond her years and has been absolutely phenomenal, what she’s done with limited minutes, she’s turned England’s history on its head and helped them reach another final.
