Campeonísimo
In the early Mexican championships, the clubs used to play a yearly tournament.Club Puebla obtained it in the 1989–1990 championships,[2] winning the League title against the Leones Negros and the Copa Mexico against the UANL Tigres.At the end of the 1995 championship, the Federation decided to play a tournament with an open and closed format, and the Copa Mexico could not be played and was forgotten, ending the list of teams to achieve the Campeonísimo.Hypothetically, the Campeonísimo title could be given due to the participation of Mexican clubs in the revived Copa MX, the FIFA Club World Cup, and the CONCACAF Champions League.The feat was achieved by Guadalajara in the Clausura 2017 season after they won their 4th Copa MX title against Monarcas Morelia and their 12th league title against Tigres UANL.
