Nov 29 (Reuters) - Wayne Rooney scored from his own half to haunt his former manager David Moyes with a first hat-trick for Everton in a 4-0 thrashing of West Ham United on Wednesday which lifted the Blues out of the Premier League drop zone.
With Sam Allardyce watching from the stands ahead of his expected appointment as Everton manager, Rooney found the net for the first time in five games by heading in on the rebound in the 18th minute after his penalty was saved by Joe Hart.
Rooney struck again at the near post and piled more misery on Moyes by capitalising on a scrambled clearance from Hart and blasting the ball past his former England team mate from inside his own half.
Ashley Williams completed the rout by heading home from a corner after conceding a penalty for a foul on Diafra Sakho when the score was 2-0, but Jordan Pickford came to the rescue by turning away Manuel Lanzini’s spot-kick.
