Efl cup west ham oust chelsea to reach quarters

I think there may be some confusion here!

Actually, it was Chelsea who won the EFL Cup (also known as the Carabao Cup) match against West Ham United, not the other way around. Chelsea won the match 3-0 on penalties after the game ended 0-0 after extra time.

So, Chelsea will be moving on to the quarterfinals of the EFL Cup, not West Ham.
