West Ham have sacked manager Julen Lopetegui after just six months in charge.
Former Wolves boss Lopetegui, 58, was appointed in May following the departure of predecessor David Moyes.
He officially took charge on 1 July, and the Hammers have won just six Premier League games during his tenure.
Saturday's 4-1 defeat by Manchester City was a ninth loss in 20 league games this season and left the club 14th - seven points above the relegation zone.
The club have held talks with former Chelsea and Brighton boss Graham Potter about succeeding Lopetegui, initially on a short-term deal.
A club statement said: "The first half of the 2024/25 season has not aligned with the club's ambitions, and the club has therefore taken action in line with its objectives."
West Ham have also parted company with Lopetegui's backroom staff, including his assistant Pablo Sanz, head of performance Oscar Caro, head analyst Juan Vicente Peinado, fitness coach Borja De Alba and technical coach Edu Rubio.
