The non-aggression pact agreement, one reached by the clubs' presidents and one that remained in force for more than 15 years, saw both clubs refrain from trying to sign talents in the opposite's academies.
However, Real Madrid are now set to sign Jesus Fortea, a right-back born in 2007 who is currently in the Cadete category at Atletico Madrid. He could now wear the white shirt three years after his signing from Levante.
A fortnight ago, a meeting took place between Real Madrid and the player's representatives in which the finer points of a future deal were established, says Marca.
At that meeting, the Real Madrid board was informed that, as a result of the good understanding, there would be a conversation between the youngster and Atletico during the week just ended. At the meeting, held on Saturday, Atletico were informed that Fortea does not want to continue his career with the club.
The reaction at the Estadio Wanda Metropolitano was one of disappointment and frustration, as they are resigned to losing one of the most outstanding gems in their squad.
