ROVERS had no answer to the Championship’s most lethal attack as they suffered a derby day hammering.
But promotion chasing Leeds didn’t have it all their own way on an incredible afternoon at Elland Road.
United had more than 30 attempts on goal as wing men Max Gradel, who scored twice, and Robert Snodgrass constantly ran Rovers ragged.
Yet Leeds had to come from behind to win and prevent plucky Doncaster from pulling off the proverbial smash and grab raid.
It was Gradel who gave the home side the lead after just 12 minutes when he picked up possession and slammed home from 25-yards out.
Snodgrass should have made it two when he rounded Gary Woods but then lost his balance, while Luciano Becchio, Bradley Johnson and Neil Kilkenny all went close as the shots rained in on Rovers’ net.
Billy Sharp then grabbed the unlikeliest of equalisers in first half stoppage time when he latched onto John Oster’s ball and poked home at the second attempt.
Rovers had hardly threatened in the final third - but four minutes into the second half they found themselves ahead when Franck Moussa drilled past Kasper Schmeichel.
It was a lead that Doncaster held for barely 30 seconds as, straight from the restart, possession was gifted to Jonny Howson and Leeds’ hardworking skipper lashed home from distance.
Rovers almost regained the lead instantly through Moussa and Schmeichel had to make a trademark block to prevent Sharp scoring his second for the visitors, who were imposing themselves and asking more questions of Leeds’ shaky rearguard.
But the decisive moment came on 75 minutes when a Snodgrass cross was knocked down for Becchio to put United back ahead.
The goal knocked the stuffing out of Rovers and Gradel, who had twice gone racing clear but failed to convert, tapped home from close range after Woods’ save from Billy Paynter to make it four.
Howson was then given the freedom of Elland Road to run clear and seal victory for free-scoring Leeds - leaving Rovers still looking nervously over their shoulders at the wrong end of the table.
