Aston Villa have sacked manager Tim Sherwood after just eight months in charge of the Premier League club.
Swansea snatched a late 2-1 win at Villa Park to condemn Villa to a sixth straight Premier League loss on Saturday -- and that proved to be the final straw for owner Randy Lerner.

Villa, who have not won since the opening day of the season, are second bottom of the table and will fall to the foot on Sunday if Sunderland beat Newcastle in the Tyne-Wear derby.
Assistant manager Ray Wilkins, first-team coach Mark Robson and performance analyst Seamus Brady have also left, with Kevin MacDonald, who has been coaching the under-21s, placed in temporary charge.
A club statement said: "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 set-up 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.
"A search for a new manager has commenced and the squad will be managed in the interim by Kevin MacDonald."
Sherwood had vowed to fight for his job, but admitted last week he had been given no reassurances over his position by chief executive Tom Fox or owner Randy Lerner.
And, after Saturday's loss to the Swans, he conceded he did not speak to chairman Lerner but used sporting director Hendrik Almstadt as a go-between.
Sherwood replaced Paul Lambert in February and guided Villa to safety last season, as well as taking them to the FA Cup final, where they lost 4-0 to Arsenal.
The former Tottenham boss leaves Villa having lost 16 of his 28 games in charge, winning 10 and drawing two.
