Roberto Martinez has been sacked by Everton with immediate effect, according to Sky sources.

The Toffees have picked up only four points in the Premier League since March 5 and the 3-0 loss to Sunderland on Wednesday stretched their dismal run of form to just one win in 10 matches in all competitions. 

Martinez, who had three years remaining on his contract, led Everton to the semi-finals of the FA Cup and Capital One Cup this season, but their poor league form has ultimately proved his undoing and he leaves after nearly three years at the club.
