Chelsea has piled on the early season misery for West Ham and its under-fire manager Graham Potter by handing out a 5-1 thrashing in the Premier League without injured star Cole Palmer.

Wearing the new Club World Cup winners badge, Chelsea was held to a scoreless draw at home against Crystal Palace, looking less than lively in their opening match. West Ham, which has spent more than $90 million to upgrade the team this summer, was crushed 3-0 by newly-promoted Sunderland.
