I see what you mean Mark but although it's percieved on here, and more widely, as cowardice, I think Henderson is actually very disciplined tactically and really holds his position, loyally playing the role he's been assigned. He needs to learn that sometimes it's also good to go for it but I think it's understandable that he isn't always taking on the responsibility for changing games himself when he has so many more experienced guys around him. Shelvey is very different of course and what's admiralbe about him is that he will try to run the game even if he has Messi on one side and Ronaldo on the other, but for all his personality and supposed skills, I don't think he's very good at football yet, at least not compared to Henderson.
