Diego was signed as an attacking player so cant see him playing as a def mid as brown and mckain have that dominated. therefore i dont see him starting as i think herbert will play brown and mckain and the wide players being bertos and hearfield. I disagree that playing 2 spoilers in the centre is negative, u need the ball to attack and then you can concentrate down the flanks. With only mckain in there and then diego/daniel bertos hearfield etc. the phoenix will be�out passed�and out muscled by the better teams even at home,�and�i dont see the phoenix midfield with the ball retention skills to be able to play with 3 attacking mids and not loose the ball. they need 2 bulldogs in there.
For me McKain and Brown did a great job steadying the midfield last year after a shakey start to the season. However as a combination in the centre of the midfield they lack the passing range and vision to set up play from the midfield. Of the two I rate McKain as having a more complete game and he would be first choice as DM, if Diego is fit then he would be a better choice to partner McKain and if he is not I'd prefer to see Ferrante given a go.
With Greenacre and Ifill our front two are much better equipped to retain possession than Smeltz, who was largely unsupported up front last season, and the need for two primarily defensive centre midfielders should be a hell of a lot less. The service from the midfield to the strikers last year was uninspiring and in my view there is only room for McKain or Brown at DM but not both, the only exception to this would be some away trips such as Adelaide and Melb where you might set out to be a bit more defensively sound at the outset.
