Chiellini does not believe De Rossi's potential inclusion in the Azzurri rearguard would cause offence to some of the specialist defenders in the squad.
"It wouldn't be a defeat for us defenders because Daniele has trained in that position and he has all the attributes to play it very well," the Juventus man said at a Press conference.
"Having 23 squad members seems like a lot, but it isn't. All the Coaches would have chosen someone else.
"Having multi-functional players gives you the possibility to change formation or ways of dealing with the opposition during the match."
