Galvan is a defender for Argentina who first showed up in Captain Tsubasa around chapter 93. He's got a solid build that gives him real strength on the field, making him a dependable presence in Argentina's defense. He wears #5.
The character's inspired by real-life player Luis Galván, though the manga itself uses different versions of his name depending on the source—Luis Galvan in Captain Tsubasa J: Get in the Tomorrow, and Gabriel Galvan according to a color spread in a special manga issue. Whether that's intentional or just happened to work out that way is unclear.
