Chelsea steamrolled past a woeful West Ham 5-1 as the heat intensified on Hammers boss Graham Potter.

After losing 3-0 at Sunderland last weekend, Potter's side have already conceded eight goals this season, the most a West Ham team have conceded across their opening two games of a top-flight season.

Jamie Redknapp called their defending "scandalous" as they found themselves 5-1 down after 58 minutes to a Chelsea team that was without Cole Palmer, who was injured in the warm-up.

The Hammers were booed off by those supporters who waited around until the end as frustrations were directed toward the board.

Lucas Paqueta had fired West Ham into an early lead with a pummelling strike from range but Chelsea found it easy to cause mayhem with West Ham unable to defend their box to the standards required. Joao Pedro headed Chelsea level before Pedro Neto and Enzo Fernandez both scored from close range to leave the west Londoners 3-1 up at the break.

Chelsea then scored twice from corners early in the second half as new West Ham goalkeeper Mads Hermansen had a home debut to forget, flapping a cross to Moises Caicedo to score before Trevoh Chalobah scored moments later from another set piece.

The world club champions shook off the dust following their opening-day goalless draw with Crystal Palace in style.

The Chelsea fans cheekily sang "there's only one Graham Potter" towards their old boss, who has won only five of his 20 Premier League games since taking charge of West Ham in January.

Redknapp: West Ham need six new signings, including changing new goalkeeper

Sky Sports' Jamie Redknapp:

"You've got to make tackles, you've got to make challenges, you've got to get after people. It was miles too easy for Chelsea.

"That's eight goals in two games West Ham have conceded. I look at that squad - I know we're only two games in - that's a squad that's going to be in a relegation fight. Unless they give the manager some help.

"They need four, five, six new signings. They haven't got the quality.

"I've seen some defending in my life... that was as bad as it gets.

"It was so poor.

"Confidence is low. The goalkeeper doesn't make it any easier - he's having a really difficult time. He probably needs to be changed.

"He's already made high-profile mistakes. [Alphonse] Areola might have to come in. He doesn't fill me with any confidence right now."
