No no, that's the conservative approach. That's the "Italian" approach. There isn't just one way of doing things.
Would you say Giovinco suites the 4-2-3-1?
There are certainly different ways of doing things, but basically you are trying to find a balance. If you have two wide wingers who don't make any effort to defend and two real forwards you are essentially playing 4-2-4. You laughed the other day at Nedved's comment about Krasic needing to defend better. In one way, I agree, because Krasic is the only wide attacking outlet in our team and needs to be given this role. Even Delneri understands that he has to let Krasic off defensive duties because of this, even though it has often left the right back exposed. On the other hand, Krasic learning better defensive positioning and use of his energy would help the team and make him a more rounded and better player. Foremost, a winger needs to attack, but the best ones are those who know where and when to balance the team.
Our attacking phase doesn't start with getting the ball wide to a winger, it starts with us getting on top of the opponent and getting the ball off them. To dictate play you can't afford to let players run down your channels at ease, that just puts you on the back foot.
If you want to dictate the play from an attacking perspective with wide attackers then these players need to be of high quality, high athletic ability, and the centre of midfield needs players who can win the ball.
Giovinco's best position is as a wide left attacker. More wide space to utilise his pace and dribbling against isolated opponents, go outside or inside on his stronger foot and good shot, whilst not being crowded in a central area by bigger opponents.
