Christopher Eccleston (in-universe)

In 2005, Perry Winkle reported to the conspiracy website Doctor Who? that he used to go to school with a boy in Salford who looked like the Ninth Doctor, about thirty years prior. (PROSE: Have You Seen This Man?)

Behind the scenes
Although unnamed in Have You Seen This Man?, the mention of a boy looking like the Ninth Doctor who grew up in Salford in the 1970s is a clear reference to Christopher Eccleston, the Ninth Doctor's actor, who grew up in the 1970s in Salford.
