The decision means West Ham are looking for their fourth permanent manager since David Moyes left London Stadium in May 2024.
His successor Julen Lopetegui was sacked after just six months in charge with the Hammers mid-table having won six of their 20 Premier League matches.
He was replaced by former Chelsea and Brighton boss Graham Potter, who oversaw a 14th-placed finish, but was sacked after only eight months in charge with the club 19th in the table.
The club opted to stick with former Wolves and Tottenham Hotspur boss Nuno despite him being unable to turn around the club’s fortunes. They were relegated at the end of last season after finishing two points behind Spurs.
Despite that, this season had a troubled start for the Hammers – they failed to win any of their first three league matches and were 19th in the table.
A run of four successive wins in the first half of September, where they scored 16 goals and went top of the table, appeared to show they had adapted to the second tier, with a 6-0 win over Wrexham the highlight of the run.
Just two league victories have come since – a 6-0 win at nine-man Lincoln City and a 1-0 victory at Swansea City came after draws with London rivals Millwall and QPR.
