Roberto is a interesting case.
After Thiago was sold Roberto, was Promoted to the first team and their were thoughts of him possibly being the new "Xavi" and was nicked named the Patient midfielder. A lot of people even me just thought he wasn't really showing he deserves to be here just seemed Average and would eventually join the likes of JDS,Muniesa,Fontas,Víctor Sánchez etc to be sold off to mid table teams.
in the summer of 2014 he signed a new Contract and to some it was like "Why?" and the few minutes he got early in the 2014/15 Season he didn't impress and a lot of us wondered "We let Thiago go for this guy?" after a little while he eventually was dropped down the Pecking order and Rafinha instead got the opportunity to shine and Roberto was left in Obscurity for awhile.
Lucho started to Experiment him in the DM position in 2015 and it managed to perform rather well there making me especially think "Man he might have a chance at being a good back up for Busi if he keeps it" Fast forward to the Summer pre season games Lucho experimented again and put him to work at RB and he performed rather well then.
The First game of the new season Alves got injured and Lucho put Roberto in at RB and since then things started looking up for Roberto he started Performing well and many Including myself started to praise him for his Performances.
With Injuries starting to Pile up with Rafinha getting a season ending knee injury vs Roma and with Messi also injuring his Knee vs Las Palmas and with Verm,Iniesta,also Being out of Action for a time and plus the transfer ban the first couple of months of the Season it just looked Grim.
If There's Positives from the Problems we've had to start this season It had to Be Roberto's Evolution. Lucho who even since the the Barca B days had confidence in Roberto, Decided to lay the chips down and Give Roberto the game time and Chances he never gotten before.
Roberto went from having a uncertain future due to lack of playing time to being one of the most Important players to Barcelona this season without a doubt. His Evolution stunned a lot of us and it's one of those times where "Man It feels good to be ended up proven wrong". He truly did cement himself as Barca Material and it's great to see with us being at the Top of the Table and January approaching it feels great despite the problems we have had during the season.
Roberto did what a lot of La Masia talents since Thiago failed to do "Impress". It's probably true if we didn't have these Injuries Roberto would've most likely never get the chance to really shine But when the opportunity came He took it and the rest is history.
Well this might sound weird but for me He's the new Luis "Lucho" Enrique. Lucho himself was a Utility player during his Prime years seems fitting he managed to convert Roberto into a player he once was
(My Grammar really isn't that good but these are my thoughts overall.)
