"You're not going to win every game. I knew it would be a tough game tonight it was a bumpy pitch and Wimbledon are a good young side," said the Pompey boss after the game.
"We've taken three points from Millwall and Wimbledon away. It was tough tonight but if we get to the Premiership we'll have to get used to that.
"Five more wins should be enough. But we've got to keep concentrating."
