I actually expect a central midfield 3 with Riera sitting deeper, Gorrin as a box to box and McGlinchey sitting higher. Cunningham and Burns to sit wider and angle their runs in towards the main striker.
In essence, you are replacing Lia with Gorrin and Carlos with McGlinchey, Brockie with Burns and then take your pick from the strikers with Stein gone. While McGlinchey is an upgrade on Carlos, I have yet to see Gorrin so hope he is an upgrade. We certainly become a bit more mobile thats for sure.
