The Reds found themselves trailing 1-0 at half-time to Jonathan Walters’ late header in the first period, and elected to bring on Philippe Coutinho and Roberto Firmino in order to serve up a response after the interval.
Indeed, the changes hade exactly the desired impacted as the visitors immediately took control of the game – and duly drew level when Coutinho swept home a loose ball inside the area on 69 minutes with an unerring finish.
And supporters had barely had time to finish their celebrations in the away section of the stadium when Roberto Firmino lashed in a second goal, meeting Georginio Wijnaldum’s ball forward with a thumping half-volley from the edge of the area that crashed into the back of the net.
