West Ham have announced the appointment of Nuno Espirito Santo as their new head coach on a three-year contract, following the dismissal of Graham Potter.

West Ham confirmed earlier on Saturday that Potter had been relieved of his duties, following a return of just three points from five Premier League games this season.

Potter lasted only eight months after succeeding Julen Lopetegui, and he departed with the second-lowest win percentage among West Ham bosses to take charge of more than one Premier League game (26.09%), higher than only Avram Grant (18.92%). 

The Hammers wasted no time in securing his replacement, with Nuno arriving at the London Stadium less than three weeks after he was sacked by Nottingham Forest.

His first game in charge will be Monday's clash with Everton at Hill Dickinson Stadium, with academy coaches Mark Robson, Steve Potts, Gerard Prenderville and Billy Lepine assisting him on an interim basis ahead of further coaching appointments being made.

"I am very pleased to be here and very proud to be representing West Ham United," Nuno told the club's website. 

"My objective is to work hard to get the very best from the team and ensure that we are as competitive as we possibly can be. The work has already started and I am looking forward to the challenge that is ahead."

Nuno led Forest to a seventh-placed finish in the Premier League last season, securing their place in European competition for the first time in 30 years.

He also clinched back-to-back seventh-placed finishes with Wolves in 2018-19 and 2019-20, meaning he has made the top seven in three of his four full seasons as a Premier League manager.

Nuno won 42% of his Premier League games in charge of Forest (26/62) – the best rate of any boss to lead the club for more than 10 games in the competition.

His win percentage of 38% over three campaigns with Wolves (43/114), meanwhile, is the second-best in their Premier League history, after Lopetegui's 39% (9/23).
