I also disagree with HCZ that a total change of system is either what is being advocated or is necessary. For me it simply needs to be tweaked to progress the ball faster up the pitch with our CM's making runs to prevent our wingers automatically being overloaded. For me, we always look first to play the same passes into space - out wide, back to centre; back to our defenders - rinse and repeat - while the team as a whole creeps up the pitch to face a set defence and a congested final third. Our only creator in MF, Odegard, spends as much of his time running sideways and backwards as he does going forwards and there is rarely anyone making overlapping runs with him from central positions.
Solving this does not require a system change, it needs less emphasis on keeping possession and more bravery - particularly as the former generally comes to nothing anyway when our moves break down in an around the box.
