It's not bannan dropping deep that is the issue, its Hutch doing it. The whole idea behind it is to draw their midfield in, creating a gap in midfield, the CH should then be able to find a gap to slide the ball, so that you can work the ball through the zones. If one does it, the other has to move forward to receive the ball in the gap. The number 10 should also then drop, creating a higher midfield. There you can work through the higher zone, to the forward wings or to slip a through ball.
When bannan comes to take the ball, hutch NEVER finds the forward space creating the impression that we play 2 deep midfielders. We then need to pass to the full backs or try the glory ball. When Nuhiu is on, he will drop deeper than Fletcher to optimise the space, but we then have no forward to play it to.
When hutch drops to take the ball, the opposition allow him to have it (milwall being a great example of this... allow him to have the ball because there is a 99% chance he will not create an opportunity). This means that there is only bannan in the middle, and he will have 2-3 men on him, effectively nullifying him. Hutch's options are then pass to a full back, who has the same options to pass forward, pass it to Lees (Borner will be marked as he is the better player) who will launch it down a channel or put his fullback in trouble, or hutch's final option is to go for a glory ball. All this time, hutch becomes another CH and exposes our midfield.
For me, you drop hutch and get someone in who knows how to play that role, ie Luongo.
But, dont listen to me, listen to the people who think he's a brilliant footballer because he occasionally does a good slide tackle! Unfortunately Bullen fits in to this category!
