Burnley boss Sean Dyche felt they controlled the game in defeat at West Ham.
An early Michail Antonio strike settle the match for the hosts.
Dyche later said, "It's rare in the Premier League to go away from home and have as much possession as we did.
"There's a lot of things right about the team at the moment but we've got to find the margins. We're close but we've got to make sure we do it rather than waiting for it to happen.
"After eight games we had two points. So we've been effective. But we need to get more effective."
