Ronald Koeman was not too pleased with his Southampton side's defence in Sunday's 3-2 defeat to Manchester United.
The Saints gave away the goal that saw United take the lead early in the second half when Maya Yoshida's horror back-pass invited Anthony Martial to race on and beat Maarten Stekelenburg for his second of the day.
In the wake of the match, Koeman spoke of the glaring error which was similar to the one made by Jose Fonte in this fixture last season.
"I hate always players, in general not criticising Maya, I hate players who pass the ball always back to the goalkeeper, play it into the space in front," he said.
"I will tell them tomorrow the same story, it is always a risk. We have to learn form that because we made that mistake last year and we did it again today.
"You can talk about tactics, and goalkeepers, offside or not offside but we lost by ourselves and not by our opponent."
