Sebastien Haller scored two first-half goals to help a much-changed West Ham beat League One Charlton in the second round of the Carabao Cup.

Chuks Aneke and Jonny Williams forced saves from Darren Randolph as Charlton had a positive spell after the break.

But Felipe Anderson sealed the win after good work from Manuel Lanzini.

David Moyes’ Hammers will host either fellow Premier League side Leeds or League One Hull in the third round.

Centre-back Issa Diop was the only player to keep his place from West Ham’s Premier League defeat by Newcastle on Sunday, but it was Haller – signed for £45m from Eintracht Frankfurt in July 2019 – who took centre stage.

He dragged his first chance wide after great skill from right-back Ben Johnson set him up, but made amends by being in the right place to opening the scoring and then finding the net with a typical target man’s header.

Alfie Doughty showed flashes for Charlton down the left and the half-time introduction of Aneke gave them added impetus, but Lanzini’s quick feet teed up Anderson and Haller came close to completing his hat-trick only to see his goalbound effort blocked by Deji Oshilaja.

Eighteen-year-old midfielder Harrison Ashby came on for his Hammers debut in the last 10 minutes as Moyes turned his attention to their Premier League game at Arsenal on Saturday.
