Birmingham City goalkeeper Richard Kingson has vowed to bounce back after his disappointing performance in Saturday's defeat to Portsmouth.
The Ghana star let a shot from international team-mate Sulley Muntari slip under his body at the near post to put Portsmouth in command on Saturday.
Kingson, 29, admitted he was distraught, but that it would not shatter his confidence.
"It was very disappointing for me and the team," he reflected. "I feel so bad about it. I was over-come that we lost that way, with me letting in a goal like that.
"It wasn't a lack of concentration. I couldn't expect it because the defender and their player were coming together, and the ball passed through the defender's legs.
"My left foot was gripped in the grass so it forced me to go down, so it became a difficult ball for me.
"I still have self-confidence, I believe in myself. This cannot take my morale away from me.
"It was my first game for Birmingham in the Premier League and I was sad about the goal and the fact we lost.
"If I get the chance to play again I am sure I will prove myself to everybody."
