th problem is that ogbonna is a left sided footballer so he will replace chiellini but we need a replacement for barzaglie (he is getting old) unless you play ogbonna on the right which would be kind of unwise.
the player will think... "ok, which team is stronger defensively..... juve. i can learn fron chiellini and bonucci and barzagli and become a better player! juve it is then!" and then rafa will cry.
maybe when BIG Champions league games come up then we can use a sub team like:
storari
isla caceres ogbonna kolarov
pogba marrone
pepe giovinco giacchierini
vucinic
so that main players get a rest
