You are still over complicating things Gus.
Statistically most goals in football today come from set pieces and when you quickly switch play. Get the ball off the opponent and, as fast as possible, try to get to the other end of the pitch and score. The way we go about things now demands extremely much from the players. You need top, top players all around pretty much. Look at Barcelona. For all their good players - in 80% of their attacks nothing happens until Messi does something spectacular.
A lot of people say Chelsea and Man U play boring football. I disagree. It makes fans happy when their team scores, and both of those clubs consistently score more than we do. They both create and entertain by having a solid defence and play quick counterattacking football with pace and power. Why don´t we try that!
In Walcott, Arshavin, Gervinho, Wilshere and RVP we have players that would excel playing that game. Let them the fuck lose! Behind them AOC, Ramsey and RYO offer more of the same.
What we don´t have these days are players that are good enough defensively to comfortably let the opposition attack us. Lure them out of the trenches, soak up a bit of pressure, and hit them on the counter. We don´t have enough ball winners for that, we are not good enough in the air for that, and we are not good enough defending as a unit for that.
A great CB, a defensively good LB, a CM that excels at the defensive aspects of the game but can still pick a pass and is mobile, and another player to complement Wilshere as the main creative hub. That´s it. Done. We are contenders again. Oh, we need another manager of course.
