Dutchman De Roo was employed as Technical Director of the Malaysian Football Association (FAM) in 2017 after the FFA Centre of Excellence (CoE) was closed down.
De Roo was also based in Queensland during his stint in Australia prior to his time in Canberra. 
However, yesterday he took to the media to criticise his own national U19s after last week’s successful AFF U18s tournament in Vietnam.
De Roo is said to have criticised the tactics of the side saying they were not in keeping with his traditional Dutch method of 4-3-3. He also is said to have criticised the side's mindset. 


While the FAM weren’t responding publicly, his comments have raised eyebrows with the federation and the country’s increasingly savvy coaching community.
The Malaysian national youth team made it to the AFF U18s final and were beaten by the Young Socceroos 1-0 last week in Vietnam. 
A successful tournament for the side coached by former Socceroo Brad Maloney after they’d beaten Australia 3-0 on the way to the final, where Lachlan’s Brook expert late goal settled the decider. 
It’s understood that even although De Roo was in Vietnam, he didn’t raise the issue.
De Roo was brought in by former FFA TD Han Berger but left Australia after making little impression on the country’s football development.
De Roo is also under a cloud after a tweet revealed part of the Malaysian FA’s DNA curriculum - which he produced as the Technical Director - appeared very similar to FFA's national curriculum presentation slides.
