The West Brom manager was not happy with referee Bobby Madley's officiating in his side's loss to Arsenal on Monday
Tony Pulis accused Alexis Sanchez of diving and insisted Jay Rodriguez should have had a penalty in West Brom's 2-0 defeat at Arsenal.
A double from Alexandre Lacazette sealed the win for the Gunners at the Emirates Stadium and moved them back to within six points of Premier League leaders Manchester City.
There was a controversial moment in only the eighth minute when Rodriguez, having been brought down by Shkodran Mustafi in the Arsenal penalty area, got back to his feet and saw a shot tipped onto the post by Petr Cech, before Jake Livermore missed the rebound.
