Doncaster manager Dean Saunders claimed his side would only get better after defeating Preston to keep up the pressure on npower League One leaders Tranmere.
David Syers scored inside the opening minute to set Rovers on their way to a second win in four days after defeating Oldham on Boxing Day. David Cotterill doubled the visitors' advantage with a long-range free-kick after 30 minutes before Billy Paynter sealed the 3-0 win from the penalty spot in the 76th minute.
Saunders' side are now just a point behind Tranmere with a game in hand and the Doncaster boss is keen to strengthen his squad in the January transfer window.
"We're up there in a good position, the team keeps improving and I can probably add names to it," said the Welshman. "If we win our game in hand we can go two points clear, so we're up there and in a good position and 46 points before January 1st is a points total I think any manager would take.
"They have to listen to me every day and it's hard work for them because they want to play five-a-side every day - but we can't. We have to be organised because that's what gets us the results, and credit to them they listen to me.
"We played well and controlled the game throughout. They didn't even have a chance, did they? We worked on the set piece for the opening goal and it's nice when it comes off."
Doncaster took the lead after just 58 seconds as Cotterill's low corner was hooked in via the crossbar by Syers at the near post before Cotterill's free-kick from wide on the left drifted in. Paynter struck from the penalty spot after Will Hayhurst was penalised for bringing down Kyle Bennett to make it eight League One games without a win for Preston.
North End captain John Mousinho said: "It wasn't a good day. It seems like a recurring process where we have a few solid results and then we've gone and produced that performance. In terms of the game itself it was bizarre.
"We'd prepared off the back of the Bury game and were looking to get a heavy home win, which we've been lacking recently, but within 30 seconds we were turning around having not defended the corner at all and that set the tone for the whole afternoon.
"Obviously there's big expectation but the best players need to thrive off that pressure but clearly we're not. Clearly we are falling short. Eight games without a win at home is poor. We should be making Deepdale a fortress and making it difficult for teams but we're not."
