"Playing at this level, we cannot make these errors and it worried us. It was a lapse in concentration.I never expected the game to end in this way."

Appiah also revealed he was not surprised by the way the USA approached the match and admitted the loss had made the group even harder.

"The USA was not going to be easy and I had said it before.I am not surprised by the way they played today.
