The Dutchman was part of the Emirates coaching set-up for two-and-a-half years before leaving in February 2017 to coach Wolfsburg.
He left the Bundesliga side in September 2017 and has now lifted the lid on life working as the Arsenal academy manager under his former boss Arsene Wenger.
Citing clubs like Manchester City, he went as far as advising kids to snub English football altogether and try their luck on the continent, following in the footsteps of Jadon Sancho and Reiss Nelson in Germany.
Jonker told the Mirror: “When I was at Arsenal, manager Arsene Wenger sometimes called up a few youth players for a couple of games in the League Cup.
“But when Arsenal had a league game a couple of days later, those boys were never in the squad. And in the next 50 games, Wenger would not pick them, either.
“So I have serious doubts if young talent are making the right step if they go to England at this moment.
“I would advise them not to go, but to play 100 games in first-team football on the continent first.
“Take Donyell Malen (PSV Eindhoven), at Arsenal, he was a big talent.
“But he left the club just in time realising he was going to end up in what I call no-man's land.
"Young players in England, who have huge talent, will only go and play in an Under-18 team.
“And, when they are improving, they then only go the Under-23 team.
“So Jadon Sancho went from Man City to Borussia Dortmund – and he is a sensation there.
“Reiss Nelson, of Arsenal, is choosing the same route. He is getting plenty of chances and minutes at Hoffenheim.”
