Moyes, who replaces the sacked Manuel Pellegrini, left the Hammers at the end of the 2017-18 season.

He recorded nine wins and 10 draws from 31 games in his first spell, leading the club to Premier League safety.

"They are getting a very experienced Premier League manager," said Moyes.

"I think there's only two or three managers with a better Premier League win record. That's what I do, I win.

"I'm here to get West Ham wins and get them away from the bottom three."

Of managers who have taken charge of more than 500 Premier League games, only two - Sir Alex Ferguson and Arsene Wenger - have a better win record than Moyes.

But he is fifth on the list of Premier League managers who have taken charge of more than 300 games, with Jose Mourinho and Rafael Benitez also having better records.

The Scot has signed an 18-month contract at London Stadium but insists he will give owners David Sullivan and David Gold "no choice" but to extend his deal.

He is still assembling his backroom staff but it will include Alan Irvine, his assistant during his first spell at the east London club.

"It showed quite a lot of class from the owners to ask me back," Moyes said. "David Sullivan and David Gold were excellent. It was very simple. I said 'I can't wait' when I got asked to come back.

"We didn't talk about the future or the past, we spoke about the position the team are in now and it went very well."

He added: "It says an awful lot about the owners that they think the job I did with my backroom staff [was good enough] to give me another chance. This time, I'm going to give them no chance but to extend me.

"There is a clause in my contract to extend the deal. I'm going to make it impossible that that clause can't be activated. It's up to the players to make sure of that now."

West Ham are 17th in the Premier League and Moyes will be in the dugout for their New Year's Day home game against Bournemouth.
