Leeds had gone into their match against Brighton on Saturday afternoon in good spirits after beating West Ham last week, but that mood was soon dampened.
Danny Welbeck netted his sixth goal of the season after just 12 minutes , and the Seagulls did not look back in what was a dominant showing.
Diego Gomez bagged a brace for Fabian Hurzeler's side, who picked up a much-needed victory after struggling against sides lower down the league so far this season.
It's not a disastrous defeat for Leeds, but their away form is starting to prove to be something that they should be concerned about in their first season back in the top flight.
