It was the first time in 2016 Jurgen Klopp‘s side had won a league match by that score and with the previous 3-0 victory at Middlesbrough making it back-to-back clean sheets there is a suggestion the Reds have become a tighter unit.
“It was a big plus for us. We are very pleased with keeping a clean sheet and also in the last game as well,” said Henderson.
“We have looked solid in the last couple of games, which is pleasing.
“As long as you win that is the main thing. We are very pleased with how we have won coming to Goodison and dominating, especially in the second half, defending solidly as a team, winning the ball back quickly and keeping a clean sheet, that’s important.”
That will give their rivals a chance to steal a march on them but Henderson insists the festive fixture schedule is irrelevant compared with the bigger picture.
“I know people say it’s Christmas and there are a lot of games but there are the same amount of games come the end of the season so it doesn’t make a difference,” he added.
“The aim is to keep performing and winning games. It is important, it doesn’t matter what time of year it is.
“We’ve always aimed to do that as every game we go into we want to get three points because we feel we are a good team who are good enough to beat anyone.
“We take each game as it comes: three points is the aim and we’ll see where we are at the end of the season.”
