Video: Albion fans discuss the 4-1 home defeat to QPR

Fine goals from Eduardo Vargas and Bobby Zamora either side of a Charlie Austin header punished Albion's slack defending and gave the visitors an unlikely 3-0 half-time lead.

The Baggies had chances but Brown Ideye spurned their best opportunities.

They improved after half-time and reduced the arrears through substitute Victor Anichebe on 58 minutes.

But they could not make any further headway and substitute Youssouf Mulumbu was sent off for an elbow on Joey Barton just 11 minutes after entering the fray and Barton added a fourth goal for the visitors in stoppage time.
