From 1 January, all players moving to England from overseas must be at least 18 years old, and qualify for entry through a points-based system.
However, through their City Football Group umbrella, the owners of Manchester City already have a significant stake in three clubs still in the European Union - Girona, Lommel SK and Troyes AC, who play in the second divisions in Spain, Belgium and France respectively.
Chelsea, meanwhile, have a very close relationship with Vitesse Arnhem - who are fourth in the Dutch top division - sending numerous players there on loan, including England international Mason Mount.
The new rules forbid English clubs signing under-18s, but there would be nothing to prevent those 'partners' doing it on their behalf.
Yup, but the problem will be any overseas clubs within ManCity's group signing players under 18 will not make it that easy for those players to become HG or Club trained for ManCity.
