Tim Sherwood has been sacked as Aston Villa manager following Saturday's home defeat to Swansea City, the club has confirmed.
Kevin MacDonald, who was demoted from his position as assistant manager by Sherwood, will replace him on an interim basis, with Tony Parks the only member of Villa's coaching staff to keep his job.
A club statement read: "Aston Villa Football Club has parted company with manager Tim Sherwood today.
"The Board has monitored the performances closely all season and believes the results on the pitch were simply not good enough and that a change is imperative.
"However, the Club would like to place on record its sincere thanks to Tim for all his efforts during a difficult period last season and for the many positive contributions he has made to the entire football setup during his time with the Club. We wish him well in the future.
"Assistant manager Ray Wilkins, first-team coach Mark Robson and performance analyst Seamus Brady have also left with immediate effect and do so with our best wishes."
Sherwood only took over at Villa Park in February and led the Villains to Premier League survival and a first FA Cup final in 15 years last term.
However, despite spending in excess of £50m in the summer, Sherwood has overseen just win win all season which arrived on the opening day at Bournemouth.
Villa are currently 19th in the Premier League with four points, and will drop to the foot of the table if Sunderland beat Newcastle later on Sunday.
