I think we need to address the elephant in the room, in that, 433 may work better without Gayle. So, the options are; plough on without him and use him off the bench or, switch back to 352/ 442.
Personally, I think 433 works for the greater good and suits more players, Phillips, Barnes, Livermore, Morrison and HRK all look better in this system not to mention all of the back 5.
I know it's controversial but, if this is the system of choice, we should pull out all the stops in January to get a replacement for Rodriguez, to play the main striker role in a 433.
