Former NAC Breda coach Stijn Vreven says they should rethink their relationship with Manchester City.

Vreven cites the sale of Angelino by City to PSV Eindhoven as reason for NAC to re-examine their partnership.

"Angelino has intrinsically high qualities, but in the beginning he was positionally and defensively very poor," says Vreven, now in charge Beerschot Wilrijk.

"He did just a little bit of what he wanted, he was not open to improvements and criticism, and we all worked incredibly hard to make the boy better.

"In the end, City paid him a lot of money and then sold him to PSV, and so I think that making the players better and selling them is no longer in balance with what NAC gets back in return."
