Premier League equals January sacking record after Marco Silva exit
Marco Silva's sacking by Watford on Sunday means there have never been more managerial changes by this stage of a Premier League season.
The Hornets became the eighth club to change their manager since the season started, when they parted company with the Portuguese following a significant dip in form since his flirtation with the Everton vacancy in October.
Sacking season started early when Crystal Palace ended their Frank de Boer experiment just four games in, with a steady succession of clubs pulling the trigger since as Everton, Leicester, Stoke, Swansea, West Brom and West Ham all followed.
Since the English top flight's rebranding in 1992, the only other season with eight changes by January was in 2007-08.
That year saw Jose Mourinho's first spell at Chelsea end in September, before Bolton and Tottenham sacked Sammy Lee and Martin Jol respectively in October.
November brought a host of changes, with Chris Hutchings axed by Wigan and Steve Bruce leaving Birmingham to replace him before Billy Davies lost his job at Derby.
Fulham parted company with Lawrie Sanchez just before Christmas, the seventh change of the season, and the eighth came on Jan. 9 when Newcastle sacked Sam Allardyce.
Last season had witnessed only four changes by this point of the season, two of those at Swansea -- though a remarkable eight teams had begun the season under new management compared to the end of the previous campaign, and Craig Shakespeare replaced Leicester's title-winning boss Claudio Ranieri in February.
The 2013-14 season can claim the record for the most managerial changes in a full Premier League campaign with 10, after Swansea and Fulham sacked Michael Laudrup and Rene Meulensteen respectively in February 2014 and Norwich's Chris Hughton and Manchester United's David Moyes followed two months later.
There were nine managerial changes in each of the 1994-95 and 2008-09 seasons.
