thiago offers more defensive contribution, tackles a lot more than pjanic, who's more creative as an attacking player. both are strong in possession, good passers. with a good dm, i think both could play in a 4-3-something formation.
Barella is not better than Pellegrini.. about Cristante - they are currently at the same level with Barella has more talent in his feet
Pellegrini is a good young player who I`d love us to get as a sub who might be good enough to be a starter in the future
Barella impressed me in few games but really disappointed me in others..
of course he's good when he's available, but do we need to spend 30m on an injury prone cb, when we have chiellini, barza, benatia, rugani, caldara, and we don't have any classy fullbacks besides sandro who's had a terrible season and might leave, we do need a monster cm who's able to tackle since vidal left, and higuain's stay is also hanging in the balance? at least thiago would be a good addition to the midfield. would cost a lot more than 30m though
