ITT people don't know the difference between 'greatest' and 'best'.
Valdes is the greatest goalkeeper in Barcelona history. Greater than Ramallets, Sadurní and Zubizaretta.
Bravo and ter Stegen are not even close. Mentioning them shows how long you've been a fan.
Yes, I am 13 and this is my first season of following Barca.
Anyway, as I mentioned above, being a legend is obviously NOT ONLY about skills, but a combination of:
1. good skills
2. being devoted to a team
3. playing here for 5-10 or more years
4. winning some trophies (having actual results in your era)
5. being Catalan or being La Masia product brings some extra points, let's be honest
6. being a part of some legendary team/historic achievement also brings some extra points
Bravo was here only for 2 years, and in spite of awesome skills and 2 La ligas in 2 years, he can't be compared with some other legends in eyes of our fans because he hasn't met other requirements like playing here for 5-10 years, being extremely devoted to a team, being a local guy etc.
About pure goalkeeping skills, Valdes wasn't better than Bravo. (Imo, they are more or less equal, or Bravo being better)
If someone thinks that Valdes was actually a better Gk, I would ask: why exactly? What has he done or what skills he possessed which Bravo hasn't?
About being a club legend, Valdes is miles infront of Bravo, because of other requirements (played here for 10+ years, won tons of trophies, a member of a golden era, a local guy, a huge love for the club both in good and bad times etc)
