It was discussed a fair ibit at the time but Henderson used as a playmaker last season on a per minute basis was one of the most productive midfielders in the league in terms of goals and assists. I think only Mata, Bale and Coutinho had better stats. Lampard I think was similar.
I don't think Hendo has the ability to be playmaker, nor is he up to it as an attacking midfielder. He is a destroyer/spoiler, a high energy utility player. a good honest pro.
His relatively poor balance and average passing game hold him back in any creative capacity, at this level. But he does bring a lot, as I say in terms of energy.
So we all know what Hendo brings to the team. But the really big question is how to get the balance right in midfield. Idealy you need a good holding player, a top draw playmaker and a top quality attacking player. One of the best in recent years has been Lampard.
As it stands now we have Lucas as the holder, Gerrard as the playmaker, but Gerrard is now limited in terms of mobility, that put extra pressure on Lucas and any potential attacking midfielder as Gerrard cannot really pull his weight.
Henderson's energy is masking the problem of Gerrards lack of mobility. Play a more creative player in place of Henderson who doesn't cover the way Hendo does could cause problems.
It's almost as if Hendo is played as Gerrard's porter - he carries Gerrards bags.
