Real Madrid Castilla coach Raul has announced Peter Gonzalez is being sold.
The winger is expected to join Valencia.
"His situation will be resolved tomorrow [this Monday]. An agreement has been reached. It was a matter of signing documents," said Raul.
"He is a boy that already in the summer he felt that his process here was over and all that remains is to wish him all the best. He has contributed a lot. He has grown a lot.
"He is leaving this bubble and we will be attentive to him and support him, as with all those who have left the Castilla."
