Ever since the change of approach from Brendan Rodgers in the middle of December, Philippe Coutinho, Raheem Sterling and Adam Lallana have occupied advanced positions troubling defenders - and have all managed to find the net since.
Following on from Liverpool's 4-1 win over Swansea City, Henderson told the Liverpool website: "Those three have caused teams real problems. Again tonight they were outstanding. They were a real threat going forward, but they also did the dirty work as well in defending, so that was very pleasing for us."
The 3-4-2-1 system has managed to get the trio into threatening positions when earlier on in the season it looked quite hard to get so many creative minded players into one side.
Liverpool have moved to five points behind the top four going into the New Year and still have Daniel Sturridge to return from injury, which would raise a few interesting questions.
Sterling is currently occupying the striker's role, meaning his is likely to change. Given the versatility the 20-year-old has shown over the past year at the club, he could be played in a role occupied by Coutinho or Lallana - or maybe be shifted to a wing-back role - a role he has filled in the past.
There has certainly be more potency about their play in recent weeks and more onus on goals coming from other areas of the side, but Liverpool have certainly possessed more of a threat in recent games - and it could relieve some of the pressure on Daniel Sturridge when he starts to get back into the side after his injury nightmare.
