"We have to look forward. We want to finish second and win the FA Cup. The first 20 minutes we had a lot of good chances to score. When they scored they put themselves in a really good situation," he said.
"By the end it was impossible for us and we're really disappointed. We wanted to repeat our triumph of last season.
"We feel we have a better team than last season and could have won it again, but in the knockout anything can happen.
"It's like Charlton in that we created a lot of opportunities but couldn't score the goal. We have to be worried about this. To win games, obviously, you must score goals. This is something we'll have to analyse and work on.
"Scoring is not just the exclusive job of the strikers. The midfielders have responsibility, too."
