Efraín Juárez, the Pumas coach, decided to resign after signing his son, Juan José Calero, as a new reinforcement for the team. The decision caused a rift between Juárez and Antonio Sancho, who wanted to refresh the goalkeeper position and give an opportunity to the young goalkeeper Pablo Lara. According to sources within the Club Universidad, the confrontation occurred when the name of the son of the Pachuca legend, 'JJ' Calero, appeared in the media as the new reinforcement of the Pumas. This information was not known by the technical staff headed by 'Efrastóteles', who immediately rejected taking a 27-year-old player who came from the Liga de Expansión after his passage through Zacatecas, Sporting FC, Gil Vicente, León and Pachuca. The question inside was: Why if they ask to exploit the basic forces of the team, they bring a footballer who has not broken through in any club? According to players to RÉCORD, the presence of Sancho was not well seen in the team. According to the players, when he approached in the convivios, a rarefied atmosphere was generated, which provoked a negative energy. Now, the intention is that with the departure of Efraín Juárez, Antonio Sancho assumes total responsibility and respects institutional decisions and not personal ones. At the moment, it is unknown if the son of the 'Condor' is from Pumas; the only thing that is affirmed is that he was a footballer who had to be under the orders of Efraín Juárez, a situation that did not occur since the Mexican strategist decided to rescind the contract that still tied him six months more with the Pedregal squad.
