Abel Hernández’s classy opener, a Jason Shackell own goal and a late Andrew Robertson strike on the counter did the damage for Steve Bruce’s men.
After a very nervy start from both teams, the Tigers broke the deadlock on the half-hour mark. Eldin Jakupović raced off his line to clear a long ball forward, which triggered a Tigers attack. Jake Livermore skilfully flicked the ball through midfield and into the path of Hernández, who took the ball into his stride and fired a powerful effort into the bottom corner from 22 yards.
That goal took the sting out of the home crowd who were in good voice up until that point – and they went even quieter when the Tigers doubled their lead five minutes before the break. There was an element of fortune to the goal though as Moses Odubajo’s shot from outside the box took a huge deflection leaving Scott Carson powerless to prevent the ball from finding the back of his net.
Despite the Rams needing a route back into the game, it was Steve Bruce’s side that posed more of a threat on the break and some better decision making from Mo Diamé and Andy Robertson could have yielded more goals.
Derby staged a half-hearted late rally with substitute Jacob Butterfield testing Jakupović with the Rams’ first effort on target on 80 minutes before the goalkeeper was brave to dive at the feet of Martin inside his own six-yard box in injury-time.
But, with the home side pushing forward, the Tigers struck a final blow with the last kick of the game in the eighth minute of stoppage-time to rubber stamp their dominance. Breaking swiftly after a Tom Ince corner was cleared, the ball was worked to Robertson on the left and he drilled a low shot into the bottom corner of the net from outside the box to send the 3,009 travelling Tigers wild with delight.
