West Ham boss David Moyes says he has a “point to prove” as he aims to “repair” his reputation at his new club.
The former Everton and Manchester United manager has replaced Slaven Bilic, who was sacked on Monday with the Hammers in the relegation zone.
Moyes, 54, has been out of work since May, when he resigned as Sunderland boss after the club’s relegation to the Championship.
“It is good for West Ham, they are getting a good manager,” he said.
Moyes, who started his managerial career at Preston North End, was voted LMA Manager of the Year three times while at Everton from 2002 to 2013 – an 11-year spell during which they finished in the top eight nine times.
He signed a six-year contract when he succeeded Sir Alex Ferguson as Manchester United boss in 2013 but was sacked 10 months into the deal.
Moyes then went to Spain to manage Real Sociedad but was dismissed in November 2015 after a year in charge.
He took over at Sunderland in July 2016 but quit in May 2017 after the Blacks Cats finished bottom of the Premier League.
“I do have a point to prove. Sometimes you have to repair things and I have a little bit to repair,” said Moyes, who has a contract until the end of the season with the east London club.
“It’s good for me, I’m back in and it’s what I love doing. I want to do well and want the team to do well.”
The Hammers are 18th, having won just two Premier League matches this season.
They spent a reported £42m on players in the summer including forward Marko Arnautovic from Stoke City for a club record £20m and former Manchester United striker Javier Hernandez from Bayer Leverkusen for £16m.
Having lost their first three games, West Ham have taken just nine points from 11 league matches, conceding 23 goals.
Following a trip to Watford on 19 November, West Ham host Leicester City and go to Everton, before a difficult run in December in which they face league leaders Manchester City, champions Chelsea and Arsenal.
Later in the month, the Hammers travel to face the Gunners in the Carabao Cup quarter-finals.
“My ambition is short term. I have to win the games,” said Moyes. “I want the football to be entertaining. But I want to start defensively. We have to start there and get some clean sheets.
“First it’s about winning football games, then it’s about the style.
“There’s a really strong squad of players here. They certainly shouldn’t be in the position they are in.”
Since moving to London Stadium at the beginning of the 2016-17 season, West Ham have the third-worst home record in the Premier League.
They have conceded the second-highest number of goals (41) in the league, with only Swansea (44) having conceded more – but the Hammers have the worse goal difference in the top flight with -16.
