Tottenham piled more misery on Premier League strugglers Derby with three second-half goals in a hard-fought 3-0 win at Pride Park.
A first half of few chances saw the Rams create the best opening when Stephen Pearson slotted Giles Barnes in but he could only flick his shot wide.
Spurs upped the tempo in the second half and created a couple of good chances down the right-hand side with Alan Hutton and Tom Huddlestone going close.
The opener came when Steed Malbranque cut in from the left and fired across goal. Roy Carroll palmed the shot away and Robbie Keane reacted quickest to slot the ball home.
The visitors clinched it late on left when Younes Kaboul showed a neat touch inside the area to create space before firing low into the net.
Dimitar Berbatov sealed the win with a cool penalty after Alan Stubbs had handled inside the area.
