The Toffees are without a win in the top flight since October and are stuck in a relegation battle in 19th place.

Everton's poor form, consisting of six defeats and two draws, is Lampard's longest winless run as a manager in league competition.

"I don't get that far down the line to fear," he told BBC Radio 5 Live.

When asked by Sky Sports if it was time Lampard was sacked, Everton owner Farhad Moshiri - who was at London Stadium to watch his team in action for the first time in 14 months - replied: "I can't comment. It's not my decision."

During Everton's poor run of league form over the past three months, the club has also been knocked out of both the Carabao Cup and the FA Cup at the third-round stage.

Jarrod Bowen scored two goals in the first half to hand former Toffees boss David Moyes a much-needed win and heap more misery on under-fire Lampard.
