What they were doing with having 2 central midfielders and no designated number 10, like in a 4-2-3-1, or 4-3-3 defensive midfield triangle, was one would sit and the other go forwards to join the build up as it advanced closer to the Iraq goal.You probably understand tactics better then me. But 442 you want two midfielders who are creating can't be all on algaich.
Val is more of a six id play him behind two other midfielders.
Valadon usually sat whilst Alagich advanced further forwards in the last 3 Asian Cup games. This is a common practice in 4-4-2s.
Last time in some earlier qualifiers I seem to remember Valadon and Bozinovski bossing the midfield against arguably inferior teams. I think Alagich played in a more advanced position as a number 10, creating a specialist attacking midfielder, in a 4-3-3 defensive midfield triangle in Ball Possession.
In Vid's current 4-4-2 both in Ball Possession and Ball Possession Opposition, he relied on the central strikers dropping back into midfield. Once again, one would drop whilst the other stayed high when the ball was in the central attacking third, or defensive third.
In the earlier qualifiers in Ball Possession, IMO the specialist number 10 worked better.
