Olivera is the key for the right side. the most creative player in the squad by far and he'll do great on that right side. zebina is good for right back cuz he doesnt attack a lot like zambro, giving the defence a lil more stability.
And Zebina at right back in a 4-4-2 is probably going to get the best out of him. playing him in a 3 man defence doesnt suit him well and thats when he gets exposed a lot.
and the reason the right side looks weaker is because having zambrotta at left back and nedved on the left wing is something no other team can compete against. so regardless, our right side would look weak even if we had stronger and well established players there.
as for camoranesi, i cant believe he was kept while others were sold to generate funds.
