Here's how its broken down by WhoScored and it seems fair enough to me. 11 assists, 2 from freekicks and 4 corners, rest from open play https://www.whoscored.com/Players/33...w/Harry-Wilson
I think an assist for the Vaulks goal is fair, everyone's expecting a Wilson shot but he backheels it, giving Vaulks a clear sight at goal between the wall and the rest of Blackburn's defence.
