Let me break this down for you.
Last night we set up like this in possession
Rushworth
Thomas-Kitching-Grimes
No one in a CDM position
MVE-Esse-Torp-EMC-JDS
BTA-Wright
The issues with this are as follows:
The distance between the 3 players who are at the back and rest of the team means that in our build up stage it is easy for the opposition to make us go long which they were set up to deal with.
The same distance/Gap between The back 3 positioned players and the rest of the team also then means that when the opposition turn the ball over they have a free run towards the 3 players we have back which allows them to overrun us in midfield as we struggle to get back to order defensive shape which is 4-4-2.
What we can do with the "same players" is set up more like this in possession:
Rushworth
Thomas-Kitching-Grimes
Torp
Rudi/Eccles
MVE-Esse-EMC-JDS
Wright
This is dropping Torp back from the basically a 2nd no.10 role he was in yesterday to a more of a 6 or CDM role and having the player at 10 operate slightly deeper than BTA was operating in last night.
This helps fill the gap in our midfield and can help to slow teams down in transition and allow us to actually get into our defensive shape
It also helps us build attacks better as having the extra 2 players deeper will give us more short passing options and allows us to attempt to play through teams rather than as what happened last night where Grimes or a CB would look up and there would be Norwich players between them and the rest of the team forcing them to play it longer.
