Chang will replace Ian Cotton, who left on 13 May after 16 years with the club.
Chang is currently a senior editor at Sports Illustrated and headed up the editorial coverage of football for the US soccer section on ESPN.com.
The news comes after a tumultuous week for the club, which saw it part company with manager Kenny Dalglish, director of football Damien Comolli and communications director Cotton.
The departures followed a disappointing season for the team on the pitch and widespread condemnation of the defiant way the club handled the Luis Suarez affair last October, in which the striker was charged by the FA for racially abusing Manchester United’s Patrice Evra.
Liverpool fan Chang strongly defended Suarez and the club on Twitter at the time and called for Evra too to be charged by the FA, stating: 'Why is Patrice Evra not getting charged by the FA? Evra admits in evidence he used insulting language towards Suarez.'
Liverpool FC declined to confirm the appointment, saying that an announcement was imminent.
