Fulham manager Martin Jol was left fuming after his team were pegged back to a 1-1 draw by Wigan at Craven Cottage.
The Londoners have now gone four successive home matches without a win in all competitions, with the last victory coming against Newcastle on 10 December.
Giorgos Karagounis' fantastic first-half strike put Fulham ahead but Franco di Santo levelled in equally impressive fashion for the Latics in the 71st minute.
"It is always the same story," Jol said. "You go one up and you need another goal but cannot score another goal and then you are vulnerable.
"It is easier said than done but when you are 1-0 up you still have to dominate the game. We had a little problem to contain them and they had players in the pockets but we are a big team at the back.
"But we needed a second goal and we did not score a second goal. It was the same against Southampton when we needed a second goal and didn't score and they scored an equaliser.
"We have a problem in our balance but we have quality and that will pull us through but we have to score two goals. Last year, if we scored one goal it was decisive. This year most of the time, it wasn't decisive."
