"UEFA defines locally-trained or 'homegrown' players as those who, regardless of their nationality, have been trained by their club or by another club in the same national association for at least three years between the age of 15 and 21"
Sancho joined Dortmund when he was 17, so he'll have 4 years in Germany by the time he turns 21, ergo he will be considered Home Grown.
Definitely can see him being a great fit in the deep midfield anchor role, assuming we can actually sign him.
Good mixture of physical size but with quality on the ball too. Ideal to sit in front of our CB’s and launch attacks.
