Plymouth manager Peter Reid was disappointed his bottom-of-the-table side did not pose more of a threat after their crushing 4-0 defeat at leaders Brighton.
Two goals from Glenn Murray and further goals from Chris Wood and Francisco Sandaza heaped more misery on the Pilgrims who were handed a 10-point deduction for calling in the administrators on Monday.
Reid said: "Brighton are a good side, but we need to be better than that. It was a struggle for us at 2-0 down, but at 3-0 we had no chance.
"We were second best all over the pitch in terms of passing and tackling and we've got to improve.
"Brighton had more energy than us. I wanted us to keep it tight, but our keeper made three good saves before they scored.
"We didn't make Brighton work hard enough basically and we must make sure we put that right at home to Colchester on Saturday."
