Telstar coach Andries Jonker is proud of his work with Arsenal's academy.
Jonker insists English clubs should show more courage in playing their young players.
He told The Sun: “What we developed is unbelievable for English standards. Iwobi, Maitland-Niles, Nelson, Willock, Saka, McGuane, Smith Rowe. Come on, those are some nice players.
“It's very nice to see them get chances. In England those 92 clubs develop a huge amount of players. But where do they go? They do not play them.
“They escape to Holland and Germany. They develop themselves and then the English clubs think, 'Let's bring them back!' It's catastrophic.
“Why do Jadon Sancho and Reiss Nelson have to go out and back? I don't have the solution.
“I believe the English need coaches with the guts to give English boys a chance. But I understand. When you can buy a foreign star for £30million, you don't take a risk on an 18-year-old homegrown player.
“It is still possible to build a really good team based on your own academy."
