David Moyes was appointed as West Ham United manager on 7 November 2017.
The Scot arrived having managed 499 Premier League matches during his time at Everton, Manchester United and Sunderland.
Moyes made a name for himself at Preston North End, where he gained promotion to the second tier of English football and narrowly missed out on lifting his side to the Premier League, losing the 2001 Championship play-off final to Bolton Wanderers.
After his success at Preston, he succeeded Walter Smith as manager at Everton in March 2002. He took over the Merseyside club when they were above the relegation zone on goal difference and led them to safety with a 15th place position.
An impressive transformation of the club’s fortunes followed and they finished seventh in Moyes’ first full season in charge.
In the 2004/05 campaign, Everton finished ahead of Merseyside rivals Liverpool in fourth position, their highest ever Premier League finish to date, and secured UEFA Champions League qualification as a result.
Moyes established the Toffees in the top seven of the Premier League from 2006/07 onwards and led the side to UEFA Europa League qualification on three occasions.
He was then appointed manager of Man Utd prior to the 2013/14 campaign, but was relieved of his duties in April of that season.
After a short time out of football, Moyes managed abroad in LaLiga where he was in charge of Real Sociedad for a year from November 2014.
Moyes returned to management in England on 23 July 2016, taking over at Sunderland following Allardyce's appoinment as England national team manager.
On 22 May 2017, Moyes resigned as Sunderland manager after the club finished bottom of the Premier League, before he replaced Slaven Bilic at West Ham less than six months later.
His efforts in the top-flight of English football have been rewarded with 10 Premier League Manager of the Month awards and Moyes has managed over 450 matches in the top flight.
