Albion were on the wrong end of two controversial decisions as Liverpool won 2-1 at The Hawthorns.
After Hal Robson-Kanu had scored his first league goal of the season, Albion were pegged back when referee Mike Dean gave the visitors a dubious free kick which led to Mohammed Salah equalising.
The Baggies then had a goal ruled out for offside when Matt Phillips was adjudged to be interferring with play, despite being yards away from Liverpool goalkeeper Alisson.
The Liverpool goalkeeper then scored a last minute header to give the visitors a fortunate victory.
