Jurgen Klopp is aware Liverpool must remain alert after moving to the top of Group C, believing a Champions League pool containing Paris Saint-Germain and Napoli will go to the wire.
The Reds thrashed Red Star Belgrade 4-0 to take top spot as PSG and Napoli drew 2-2 in France, with Angel Di Maria's late goal nudging Napoli off the summit.
But Klopp roared with laughter when asked if there was still work to do to ensure qualification, the Liverpool boss looking no further ahead than a trip to Serbia in a fortnight's time.
"I don't even know who is second, but I heard they played 2-2 with the equaliser pretty late," he told BT Sport.
