Goals from Andreas Weimann, Jacob Butterfield and Richard Keogh have earned Derby County a comfortable 3-0 win against Rotherham United.

It took Derby just seven minutes to open the scoring at the iPro Stadium, with Weimann, in the side as a replacement for Thomas Ince, netting from close range after neat work from Butterfield and Craig Forsyth.

Johnny Russell and Bradley Johnson both wasted opportunities to double Derby's lead, but just before the break, Butterfield extended their advantage with a long-range strike into the corner.

Weimann came agonisingly close to scoring his second and Derby's third soon after the interval, but despite lobbing the ball over former Rams goalkeeper Lee Camp, Danny Collins was able to make the clearance off the line.

Rotherham were offering little in the way of attack, and with 14 minutes remaining, Derby put the game out of their reach as Keogh clinically found the net from close range.

The Rams were unable to find a fourth but manager Paul Clement will be delighted to have witnessed his side extend their unbeaten league record to nine games.
