West Brom have reacted to a miserable sequence of one Premier League win in 25 matches by sacking their chairman John Williams and chief executive Martin Goodman and placing them on gardening leave.

“These changes follow Albion’s poor results this season which currently sees the club at the bottom of the Premier League,” a club statement said.

The club changed manager in November, appointing Alan Pardew to replace Tony Pulis. A defeat by Chelsea led to Pulis’s dismissal and this latest move follows a 3-0 loss at Stamford Bridge on Monday.

West Brom’s only league win since they started the season with successive victories came against Brighton on 13 January. They are five points adrift at the foot of the table.

Mark Jenkins is returning to be the club’s CEO, a role he previously held for 14 years. “There is much to do but for now the focus must solely be on the remaining games of this season,” Jenkins said.

The owner, Guochuan Lai, bought West Brom from Jeremy Peace in 2016 and appointed Williams, a former Blackburn chairman. Albion were last relegated in 2009.
