The Anfield club went six points clear at the top of the Premier League table after winning their early kick off.
It was a remarkable performance considering they also picked up a recent 2-1 victory over title contenders Tottenham Hotspur in midweek, putting Jurgen Klopp’s side back on top of the English top flight.
And if the reigning champions were delighted with how their performances have hit top gear recently, it was clearly on show from Henderson after the match.
“We were ruthless today,” the England international told BT Sports at full time.
“We took our chances, dominated the game for large periods. We were a little bit sloppy at times but delighted with the performance and result.
“It was coming, over the last few games we've had some chances and not taken them and it has cost us at times.
“Today we managed to finish our chances, which is always important in football.”
"In some ways but we don't just look at the scoreline. I thought we were very good midweek and again today so we just need to keep the momentum going and work hard," he added.
"In the first half they had one or two half chances - a little on the counter-attack. They are always going to create something but we limited that today. We managed the game well in the second half.
"Overall, the performance level, we have to be happy. Now we have a week leading to the next game. Then another tough test again."
