West Bromwich Albion have announced they have parted company with their head coach Tony Pulis.
He departs after the 4-0 home defeat by Chelsea on Saturday left West Brom in 17th, one point off the relegation zone.
Pulis had been at the club since January 2015.
“These decisions are never taken lightly but always in the interests of the club,” said West Brom chairman John Williams in a club statement.
“We are in a results business and over the back end of last season and this season to date, ours have been very disappointing.”
Pulis is the fifth managerial departure in the Premier League this season following Frank de Boer from Crystal Palace, Craig Shakespeare from Leicester City, Ronald Koeman from Everton and Slaven Bilic from West Ham United.
Assistant head coach, Gary Megson, has agreed to take charge of first-team affairs until further notice.
West Brom, who are on a 10-match run without a top-flight victory, are next in Premier League action at Tottenham Hotspur on Saturday 25 November.
