The 19 year-old centre-back joined the Dutch giants two weeks ago from Melbourne Victory, and while he will play for the club’s under-23 team in the Netherlands second tier, he is expected to also train with the first team as he chases his dream deal.
Recommended by his management team to PSV, Deng cemented their interest after playing for Australia's Under-23 side, the Olyroos, against Vietnam last January in Qatar – even though he was forced off with injury after 75 minutes.
Deng, who has two seasons left on his Victory contract, is vowing to add gloss to every aspect of his game at the club that was once home to Archie Thompson and former Socceroos star Jason Culina.
"I have a lot to play for and a lot to prove," said Deng, who came to Australia from Kenya as a six year-old and made 13 appearances for Victory in a breakthrough campaign last season.
"The Eredivisie is a top league and is known for producing so many great players. I would love to play there one day.
"I will critique all aspects of my game: I am aiming to improve the aerial side (of things), get stronger and faster, improve my weaker leg ... really just get better in every way.
"If I do really well they will offer me a two-and-a-half year contract ... I have a lot to play for at a really great club.
"I also have two years at Melbourne Victory and if it doesn’t work out, I go back I will go back there and keep progressing. Right now, I am on a big learning curve.
"They (PSV) saw me play for the Olyroos against Vietnam and my agents John Grimaud (and his European partner) Jan van Baal were there, and even though I missed the next match with injury I guess they saw enough."
Deng, who has been training with his new under-23 PSV teammates for the past fortnight, said: "They are very technical and physical. It’s been a good challenge so far.
"They have a wonderful set up at the club ... a great juniors program. Hopefully later on I’m can start training with the senior team.
"As each session goes by I’m getting used to the boys and I feel I am settling in."
Modelling himself on Real Madrid's master defender Sergio Ramos, Deng said: "He's somebody I love to watch."
"He's a great leader and a great tackler, who's also superb on the ball and dominating in the air. He's one that I certainly idolise.
In tandem with his ambition to break into the Eredivisie, Deng also has eyes on debuting for the Socceroos at some stage.
"I would love to play for Australia one day ... that’s another career goal I am setting and being based in Europe would probably help that ambition," he said.
