The Man With The Stick said:
If we play five in midfield next season we'll be fine. We look a lot better starting with only one striker, seems to suit our possession game.
I too like it but we also play well as a 4231. We just need to play the right players.
Too many times I think Mancini has tried to shoe horn players into the team to stop them moaning from not playing and keep the squad fresh. It could be argued that his is own fault.
As a club we need to find one formation and stick to it, we then only go and get players who will suit this formation.
You don't see Barca buying Grant Holt so he is "another option", they buy skillful, fast, quick footed possession players and every single game they go out and play the same way for 90mins.
If the rumors are true and we are going to move to a 4-3-3 system like Barca than that is fine. We just need to sell the likes of Kolarov, Lescott and Dzeko but then bring in someone like Digne who is similar to Clichy; quick, strong, capable of going forward and defending, Marquinhos who is similar to Kompany in that he is; quick, reads the game well and plays football and finally someone like Sanchez to replace Dzeko; very quick with the ball and without, capable of scoring and creating, capable of going down the outside or cutting through the middle.
Also what has been mentioned before is a deep lying playmaker eg Benat or Fernandinho is crucial to this formation working.
Here is an example as to how we could line up...
Silva---Aguero---Sanchez
----Yaya-----Benat
--------Garcia----------
Clichy-Nast--Komp-Richards
---------Hart--------------
Front three are all capable of drifting around the front line, Yaya can go forward and influence play as well as defending going back the same with Benat.
Garcia will sit in the midfield and just keep possession ticking over and provides a threat from set pieces.
Our back four doesn't need explaining, Having Richards back in there though is a huge boost to this formation working.
The starting 11 above can all be rotated as well for the likes of Milner as a CM or winger, Barry as CM or DM. Full backs rotate as normal and CB's as well.
Guidetti can rotate as a striker or maybe out wide? not naturally very quick but possibly could do a job if needed, maybe even someone like Suarez? could step up as well?
