West Bromwich Albion moved top of the Championship by thrashing a woeful Cardiff City 4-0 in the Welsh capital.
Karlan Grant hammered Albion ahead in the fifth minute with a powerful effort from the edge of the penalty area.
Curtis Nelson's calamitous own goal doubled Albion's lead on a night when the Cardiff fans booed their side off the field at half-time and full-time.
Alex Mowatt crashed home a sumptuous third with 15 minutes remaining and Matt Phillips tapped home a fourth.
Albion are top of the Championship with 22 points after their stroll in south Wales, while Cardiff slip to 16th after a fourth straight defeat that prompted an angry reaction from the home fans.
