United go to Anfield top of the table by three points.
“Losing at Southampton was absolutely not what we wanted," said Klopp.
"But the next day (after a day off) we spoke and the boys had their say as well, all that kind of stuff.
“We are now in a place where we want to be. We know what we have to do.
"We know what went wrong. We want to change. Now, we have to put in place on the pitch. That is the situation."
Klopp was in defiant mood as he detailed the response of his players to their recent poor run of form which has seen them take two points from the last nine.
Discussing United manager Ole Gunnar Solskjaer, he replied: “I'm really looking forward to this game, to be honest.
"I know Ole said that this is the best moment to play against Liverpool… yeah? Let's see."
