Manchester United captain Bruno Fernandes says they must not dwell on their humiliation at Liverpool.
United lost 7-0 to leave their away support embarrassed.
Fernandes said, "It is very frustrating, disappointing, sad because it is a really bad result. We came here with a different mindset before the game.
"The first half was really good from ourselves, we had a lot of chances. We controlled most of the first half I think, they didn't create that much.
"[In the second half] we tried to go forward and score goals and we lost a bit of balance. We gave too much space away against this kind of team. We have to avoid that.
"The games are coming thick and fast. We had setbacks in the past and we have to come back quickly again. This is what Manchester United are about, we can go down but we have to get back up."
