Sunderland goalkeeper Costel Pantilimon admits talk of their rout at Southampton is banned.
The Black Cats have enjoyed a revival since that low point.
Insisting last month's 8-0 thumping at Southampton is firmly behind them, Pantilimon said: "That was an accident game. We don't like to discuss that now.
"It was important our reaction was positive after that and we have shown that mental strength. We have reacted well. I don't want to discuss that game anymore, it's gone. It is in the past. It is finished. We like to move forward.
"It is true that I have got my first clean sheet now. It is good for the team's confidence and for the team to have good results. We have to try to continue like this and grow together."
