He said: "We don't need to lift our players. I think to compete with a very good Charlton team for 60 minutes we have got to take positives out if it.
"It was disappointing to lose like that, but we were quietly pleased that for the first 60 minutes of the game we were the better side.
"It was a good game with a good atmosphere and it was the sort of game that we want to be involved in week in and week out, but it will take time.
"The outcome of the game was changed by the ref's decisions."
