But isn't that the crux of the matter. 'Building' which takes time with the resources you have or buy in. We seem to be very effective defensive unit away from home with a 'defensive plan'. Sit tight with 2 defensive midfielders, and Barkley dropping a bit deeper and when we get the ball, move it though the midfield towards the attack, with a fullback or both bombing on. And then playing it in the oppositions half to create chances and score goals. 12 goals in 12 aways and half them clean sheets, one defeat drawn 7 and won 4.
Martinez and the players are finding it difficult to replicate our away defensiveness at home. In a way the debate has now become how do we start winning at home. Do we play too gung-ho at home and should just sit back and absorb pressure and hit teams on the counter? Should we as the home team take the game to the opposition and go at them? Martinez has tried to make us more solid at the back with Robles, Coleman, Jags, Mori and Oviedo and we have looked more solid, having conceded 1 in 4 games.
Martinez is building a young squad that can compete and it will take time as inconsistency is the hallmark of being a young player. Whether that is those playing in goal, at the back in midfield or attack.
It would be very hard to find a 'handbook of football expertry' that would show how any particular team, with any set of players, young, old and indifferent, injured or not injured, playing in this or that position, should be achieving this or that. Whether a team'squad is 'under achieving or over achieving' is a big statement to make.
