Karlan Grant's late strike took West Bromwich Albion top of the Championship but they will have to play much better than this to be still there at the end of the season.
Bournemouth can climb back to the summit if they avoid defeat at Bristol City on Saturday and even though Grant’s 75th-minute goal was enough here, Albion made hard work of it in a tough derby clash.
Birmingham are now without a goal in five games yet there were unlucky not to claim a point. Ivan Sunjic hit the bar and Scott Hogan squandered two good chances.
