Struggling West Ham United said on Sunday it had appointed David Moyes as manager for the second time in a bid to safeguard its place in the English Premier League.

Former Everton and Manchester United boss Moyes succeeds Chilean Manuel Pellegrini, who was fired after a 2-1 defeat to Leicester on Saturday that left the Hammers just one point above the relegation zone.

The 56-year-old Scot has been without a club since leaving West Ham after a six-month spell in the 2017-18 season.

Moyes guided West Ham to safety that season after Slaven Bilic was dismissed in early November and will be tasked with doing the same for a second time.

"It's fabulous to be back," said Moyes in a club statement.

"I'm feeling very proud that I'm back here at West Ham. But I think more importantly I'll be looking to see what I can do and what I can make improvements to."

Moyes won nine and drew 10 of his 31 previous games in charge of the club.

He made his name in 11 successful years at Everton, but was fired after less than a year as Alex Ferguson's successor at Manchester United.

Moyes also struggled in short spells at Real Sociedad and Sunderland before taking the West Ham job first time round on a short-term contract.

He was not offered a new deal despite comfortably keeping the club up by finishing 13th.

However, West Ham's ambitious appointment of former Real Madrid and Manchester City boss Pellegrini did not pay off as the Chilean was let go on Saturday after a run of seven defeats in nine Premier League matches.
