Someone in the club hierarchy decided 3-4-3 was it!
That's why Ruben is here, he has to find which players in our employ right now, can function in the 343 and that is the whole purpose of what he is doing, right now.
Maybe in his prelim with Sir Jim he has been promised other players, but who and when? More likely he has been told sort those out who can play the way you want and sell the rest. For example it could even mean such as Martinez leaving, he is a very good Left CB in a back 4, but not in a back 3, he needs someone outside him.
These are the sort of risks of course, where good players in our current system (at least playing with a back 4) such as Martinez may need to go; we will get more for him than we paid, which would be something of a miracle at this club.
The worse risk of course is being drawn into a relegation 'dog-fight', but no one wants to hear that, its ridiculous, isn't? However if it was to occur, does anyone seriously think the current squad could win out in such a struggle?
However, lets be honest a few more results like Bournemouth and Wolves will start to give fans terrible nightmares, like we had in the 70's when reds fans woke up screaming..... " no, no, no... we are too good to go down"... "there are others worse than us..." etc. Then the nightmare became a reality!
It's more than likely if Ruben can't sort out a squad that can play effectively in 343, from the ones he has, Sir Jim will have to have another little chat with the manager. The problem may well be that with Ruben's approach appearing to be 'whatever happens the sun will still rise tomorrow', he seems to present himself like the eternal optimist.... if so, then yet another 'back me or sack' scenario begins to form at OT.
Meanwhile the ship is drifting with the tide!
