I don't understand the inclusion of Cantú and Giménez. Giménez played around 10-15 games per season in the four seasons he spent at Huracán, firstly as a center-back and later as a right-half: he doesn't deserve to be named in the first team, let alone in the best XI. Cantú, while more deserving, is shadowed by many other more important defenders in Huracán's history. While his 193 games in 6 seasons might be impressive, he wasn't even a first option in Huracán's 1973 Torneo Metropolitano winning team - those were Basile and Buglione. My suggestion is to change those two for Alfio Basile and Rodolfo Graieb. I also think it would be more fitting to add Juan Manuel Filgueiras to the first team over Pedro Barrios, who can still go to the reserves.

The midfield is almost perfect. I would just switch Emilio Baldonedo to the forwards' section and add Sebastián Viberti, who is alongside Coco Rossi their best defensive midfielder ever. The team has 22 players instead of 23 so I think this would be the better change.

Since I believe the reserve section is lacking some names, I would like to mention the following: Marcos Díaz, Héctor Roganti, Juan Fernando Pratto, Carlos Nóbile, Alberto Fanesi, Carlos Leone, Gastón Casas (who as nicoferrari said, was a forward/attacking midfielder, not a defender), Ramón Vázquez, Claudio García, Antonio Barijho and Juan Carlos Salvini. The other players TheGreatRossonero put on reserves are okay, they all deserve a spot in the team.

And last: this might be a controversial take, but I believe Stábile doesn't fit in the team's Best XI. Despite his massive legendary status at the club, his position on the field is extremely well covered by Herminio Masantonio. The current Best XI has him as a second forward when he never played in that position neither for the club nor the National Team, and if you decided to put him at RW (which definitely wasn't his best position) there's already René Houseman. And while Houseman can play winger on both sides of the pitch, if you were to change Houseman's preferred RW position to LW, it would be more fitting to have Méndez as a right inside forward: you can't take Masantonio out for Stábile and if you are going to switch Houseman's side, it would be better to have a player whose preferred position is actually on the right side. My formation looks something like this:



GK BALEY
CB ALBERTI
CB BUGLIONE
RB CHABAY
LB CARRASCOSA
DMF ROSSI
AMF BRINDISI ©
