Tony Pulis has been sacked as West Brom head coach with the club a point above the Premier League relegation zone and without a win in 10 top-flight games.
The Baggies were beaten 4-0 at home by Chelsea on Saturday. Albion won their first three games of the season, but have drawn four and lost seven since beating Accrington in the Carabao Cup on 22 August.
Former West Brom manager Gary Megson, who had been Pulis’ assistant, is taking over “until further notice”.
Chairman John Williams added: “These decisions are never taken lightly but always in the interests of the club. “We are in a results business and over the back end of last season and this season to date, ours have been very disappointing.
