Brighton manager Gus Poyet warned his table-topping side that it would be "back to basics" in training despite another classy display in a 4-2 win at Bristol Rovers.
The Uruguayan was unhappy with the manner his side conceded two goals at the Memorial Stadium, even though his team built a 4-1 lead and comfortably claimed the points.
Poyet said: "We scored four goals, but conceded two. I prefer scoring one or two and conceding none. To do well in football you need to be strong at the back and we have to go back to basics defensively."
Will Hoskins gave Rovers a shock lead, but Ashley Barnes equalised and then supplied the pass for Elliott Bennett to put Brighton 2-1 up.
Barnes shot rebounded off Rovers goalkeeper Luke Daniels on to defender Cian Bolger for an own goal in the 74th minute and Glenn Murray headed Brighton further in front before Hoskins fired his 17th goal of the season as a consolation.
Poyet added: "We don't concede many and when two go in in one game we don't like it."
