Ramón Díaz
Ramón Díaz the Argentinian coach of the Paraguay NT that defeated Brazil in a penalty shootout last night was part of Inter 1988-1989 team that won the Scudetto beating Maradonas' Napoli in second place and Baresi, Maldini, Rijkaard, van Basten and Gullit's Milan in third place. Díaz was the second top scorer for Inter that season with 12 goals behind Aldo Serena with 22 goals.
Other notable members of that Inter team were Walter Zenga, Giuseppe Baresi, Giuseppe Bergomi, Andreas Brehme, Lothar Matthäus, Nicola Berti and Aldo Serena. Giovanni Trapattoni was the coach. That Inter team holds the record for most points in the 18 team (2 points per win) format with 58 points of 68 available for the season.
Milan won the European Cup (Champions League) that season.
Napoli won the UEFA Cup (Europa League) that season.
Basically that was one of the best seasons for Serie A ever.
A fun fact is that Ramón Díaz was Maradona's most hated rival, in fact Maradona stopped Carlos Bilardo (Argentina NT coach) from calling Díaz to the Italy 1990 World Cup.
Another fun fact is that the 4 teams in the Semifinals of Copa América are beaing coached by 4 Argentinians: Jorge Sampaoli (Chile), Ricardo Gareca (Perú), Gerardo Martino (Argentina) and Ramón Díaz (Paraguay).
