Graham Potter will be appointed as West Ham's new manager after the club sacked Julen Lopetegui.

Former Brighton and Chelsea boss Potter has agreed a two-and-a-half-year deal with the Hammers and will be unveiled at a London Stadium news conference on Thursday morning.

Spaniard Lopetegui was sacked on Wednesday after just six months in charge.

The former Wolves boss, 58, was appointed in May following the departure of David Moyes but officially took charge on 1 July.

During Lopetegui's tenure, the Hammers won just six Premier League games.

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.

West Ham said in a statement: "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."

The club 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.

"The board would like to thank Julen and his staff for their hard work during their time with the Hammers and wish them every success for the future," added the club's statement.

"The process of appointing a replacement is under way."
