Henderson bothers me. I really, really like him as a player. I think he has loads of ability, and I know he sees the field extremely well. For some reason, though, he looks scared to attempt anything even remotely dynamic, and when he does, he's hesitant and it doesn't come off. It's like he has a filter between his mind and his feet that more dynamic midfield players lack. He looks like he's thinking about what his coaches want him to do, rather than just playing.
He really needs to be dropped for a bit. Playing is just hurting his confidence at the moment. I think the system isn't very flattering for him, but he also isn't doing himself any favors.
Let Shelvey get a few games in his place. Looks the better player at the moment. Think Henderson just needs to sort a few things out mentally.
