Starting point should be to solve not having Gana and Scneiderlin playing together in a 4-2-3-1.
The argument that we don't have anything better, that its the safest most reliable option, should be long gone by now.
I can't see Silva going there again and if he does there has to be serious question asked about what the hell is going on.
The deficiencies in the two players can not be wished away. To put them as a 2 exposes the defence and offers little to the players in front.
Its not fair on the players behind or in front of them and its especially not fair on them.
The fact is, there is no combination of players available that could play the 2.
And its a big if that Gomes will slot in to the 4-2-3-1 and solve the problems.
The formation needs to be binned for at least the foreseeable future.
