According to Metro, Aisha Saini was on holiday in Spain and playing in a sports tournament at La Manga when she impressed AC Milan scouts.
She was then approached by the club, who signed her up for the prestigious annual European academy tournament in October.
Daniele Paccagnan, AC Milan academy's head coach, enthused: "We were amazed how strong she was. More importantly, she has excellent control and technique, and her attitude during practice was fantastic."
Saini will become the first girl ever to take part in the event.
She recalled: "I didn't know the coaches were watching me until they told us after the final training session."
Saini's father Michael added: "We are so proud of her. We just enrolled her to keep her busy because we thought she might be bored.
"The scouts said they have never asked a girl to join their academy before, but they saw her play and knew immediately she would be able to hold her own among a load of boys."
