AZ Alkmaar technical director Max Huiberts has lifted the lid on their deal for Félix Correia.
City signed Correia in the summer window before loaning him out to AZ Alkmaar.
And the Dutch club's technical director claims there is an agreement in place to partly own the youngster.
“We have now made an agreement with Manchester City allowing us to partly become the owner of Correia, without us determining where his future lies," he said.
"Maybe that will later lead to further cooperation with City."
