The Toffees were knocked out of the Carling Cup by Brentford on penalties.
Irish fullback Coleman told Absolute Radio: "Yeah, you know, everyone's bitterly disappointed with the result and that, and we had a lot of chances and obviously we should have took some, and it's just unfortunate on the night, but no excuses really....
"It was always going to be a difficult place to go, League One, and they were going to be fighting for everything against the Premiership Club, and fair play to them, they got the result on the night, but we should have done a lot better."
