Arsenal boss Arsene Wenger has admitted that he is still haunted by last season's Carling Cup final defeat to Birmingham City.
Obafemi Martins scored a last-minute goal to clinch the cup for the Midlands side at Wembley last February.
"Yes, it will hurt me forever because we never forget disappointments," Wenger said.
"That's part of life at a managerial level, you do not only have successes but disappointments, too.
"People forget we fought very hard to get there and, overall, we produced great performances in the Carling Cup last year."
The North London club host Bolton tonight to contest a place in the quarter-finals of the competition.
