But it was a measure of how the German has rebuilt the Liverpool squad that they were so dominant.
It was one-way traffic from the start, making it a nightmare evening for Derby’s 21-year-old keeper Jonathan Mitchell who had been drafted in for only his second senior game after illness to Scott Carson.
In fairness, he couldn’t be blamed for the goals – the first came when captain Richard Keogh horribly sliced Coutinho’s corner and the ball fell to Klavan who couldn’t miss from four yards.
In fact, Mitchell kept Derby in the game for a while.
But right after halftime Liverpool cut through Derby’s defence again, Coutinho finishing off Firmino’s incisive pass.
And then another flowing move put Origi through to crash home and seal victory.
