Albion have literally been cut wide open by a simply formidable unit in Liverpool.
The visitors have had virtually all the possession in the first half.
Emre Can headed in a corner on the half hour.
Less than a minute later Philippe Coutinho sliced Albion open and Roberto Firmino emphatically placed his shot passed Maty Ryan.
Albion’s best chance fell to Glenn Murray who hooked his shot wide when well placed.
It looks likely that Solly March will replace Izzy Brown in the second half.
