London - Carlos Carvalhal and Paul Lambert's departures from their clubs on Friday mean there have now been a Premier League-record 15 managerial changes this season.
Swansea announced they would not renew Carvalhal's expiring contract and Stoke, also relegated, quickly followed suit by parting company with Lambert.
The pair followed Sam Allardyce (Everton) and David Moyes (West Ham) in leaving their roles in the week between the end of the league season and Saturday's FA Cup final.
Add in 10 changes during the league season and Arsene Wenger's pre-announced departure from Arsenal after their final game against Huddersfield, and this season has now surpassed the previous record of 13 changes.
Defining a season as the period from August 1 one year to May 31 the next, the previous mark was set in 2013/14 after a similar end-of-season flurry.
