Tony Pulis fifth Premier League manager to lose his job
Tony Pulis' sacking by West Brom is the fifth Premier League dismissal of the season already.
The number of top-flight sackings was already at a five-season high even before the Welshman's exit, with four up to November 20 compared to the next highest mark of three by the same stage in the 2015-16 season.
The bosses fired so far this season are Frank de Boer (Crystal Palace), Craig Shakespeare (Leicester), Ronald Koeman (Everton) and Slaven Bilic (West Ham).
By this stage in the 2015-16 season Liverpool had sacked Brendan Rodgers and replaced him with current incumbent Jurgen Klopp, Tim Sherwood had been axed by Aston Villa and Dick Advocaat had been dumped by Sunderland.
The Black Cats were also responsible for the only sacking by this stage in the 2013-14 season, when they dismissed Paolo Di Canio.
The only dismissal by this stage of last season was at Swansea, who sacked Francesco Guidolin.
There had been no sackings in the Premier League by this stage of the 2012-13 and 2014-15 seasons, but the first of those seasons did feature two dismissals before the end of November - Roberto Di Matteo at Chelsea (November 21) and Mark Hughes at QPR (November 23).
