the midfield is not weak but it's unexperimented which all that include : ups and downs
it depends on their fitnesses at the moment i think!!!
petit, viera, overmars can't be replaced so easily , it's just a big hole since they left, look it's like in french team what will rest when zidane, makelele and thuram will leave? young and unexperimented players ............at first sure it'll be though but their level will increase, their confidence too and they'll make good players
as we say in france Roma didn"t built in one day
