I actually think it could well be time, to try out a 4-3-3, i don't think it will happen and we have had a completely full squad to try out the 4-2-3-1, with several attacking players missing, but i haven't been too impressed with Lampard Mikel either, but it is too soon to be definitate about it. Main advantage of the 4-3-3 is that it will suit a player like oscar as well as ramires which could well be good... Still could have similar problems, but there would be less of a strain on one DM. Now whether we will change, i highly doubt, i think in theory the 4-2-3-1 looks ideal, and it may be hard to change it fully with only one preseason game left...
