Alan Pardew is on the brink at West Brom after the Baggies capitulated to a damaging 4-1 defeat to Leicester.
Jamie Vardy netted a stunning volley before Riyad Mahrez, Kelechi Iheanacho and Vicente Iborra sunk the Baggies.
They cancelled out Salomon Rondon's early opener for the hosts.
It was Albion's seventh straight defeat in all competitions and they remain bottom, eight points from the Premier League safety line, as the Foxes sit eighth on 40 points.
Boss Pardew's job is in the balance with the managerial situation now a fluid one at The Hawthorns.
It is expected to be reviewed after another damaging defeat with the former Crystal Palace boss having won just once in 16 league games since taking over in November.
