Glad to see him proving doubters wrong.
Rafinha played well recently, but saying that he proved doubters wrong sounds as if he played in a spectacular way against top opponents.

He played only in all matches against weaker opponent.
Imo, it is hard to judge any of our players against these Mickey Mouse opponents, since in 90% of matches against those weaker teams when our team plays well:
1. Roberto looked like a world class Cm and Cdm
2. Munir looked like a real deal
3. Rafinha was very good as a Cm
4. in the past, Bartra looked like Bartresi against those crappy teams etc
Of course, there are some players like Montoya, Vidal, Douglas, Sandro, Gumbau and currently Paco who managed to play poor even against those weak opponents.
My point: when our team plays well against poor teams (when we have MSN), then even average players can put world class performances and we might get an impression that they are better than they actually are.
On one hand, almost all of our current players (except Vidal and Paco for now) are too good for 80-90% of La Liga teams.
But for a level of RM, Atletico, Sevilla, CL top teams and similar, then we can see how some of our players are of a world class level even for top matches, while some guys are just squad players and excellent for (Barca's) La liga level.
Till now, only Iniesta, Rakitic and Busi proved that they are world class level of midfielders for biggest matches.
Arda will show what he is capable of in this season.
Gomes has potential, but he is yet to prove/show what he can.
Rafinha, Roberto, Denis are still miles from proving that they are on required level as midfielders for the biggest matches (for lots of biggest matches in a row).
(Someone will reply: BUT Roberto played well against RM at Bernabeu in 2015. Again, it takes more than matches against weaker teams and more than 1-2 matches against top teams to earn a reputation of being good enough for the highest level of competition.
Even Bartra had good matches against PSG and AM 2-3 years ago.)
But, for the end, tbf Rafinha DID improve against weaker teams.
In the past, he was all over the place and most of the time one of our worst players on the pitch.
Lately he has been much better against weaker teams than before his injury.
