Except in a diamond midfield you should have two Central Mids playing in front of the sole DM. Camo can function as a CM, but Gio definitely doesn't have it in him to play that role.
What Yamen meant, was Camo and Gio functioning as wingers, Diego as the attacking mid behind the two strikers and just one DM. Thats a formation nobody plays in modern football, the defense would get too exposed, the DM would have his work cut out for him and would probably be outnumbered and the midfield would just get stretched.
I believe it is over adventurous and would never work.
