But Pezzella is not set to seal a move to Europe with Newcastle, his representative has stated.
Eduardo Palomar - the lawyer of the player - says: "We are going to do all what is possible for letting German end his formation at River, and once he has an important part of his career done he will be transferred to a team from abroad.
"There is a total agreement with the officials of River Plate for letting Pezzella play for some time at River until he gets a regular position in the first team.
"He is at his first step of a long ladder. He is happy at this moment and after all the patience he had for being able to play at River, he doesn't have in mind to leave, River is his home."
