The development comes a day after The World Game reported three major European clubs - Bundesliga's Stuttgart and English giant Liverpool believed to be among them - are keen to sign the 21 year-old midfielder.
Rojas scored 15 goals in the 2012-2013 A-League season on the way to becoming the first player since Mark Viduka to win the Player of the Year and Young Footballer of the Year on Monday.
"I have absolutely loved my time at Melbourne Victory, from the always-loyal fans, to the support of my teammates as well as the coaches and the staff – they have all definitely helped make me who I am today and I can't thank everybody enough," Rojas said.
"It's every footballer's dream to play in Europe and I'm over-the-moon to be able to say I'm about to live that dream very soon.
"I definitely will be keeping a close eye on Victory while I'm overseas and won't be surprised to see the club achieve even more success in the future."
Victory coach Ange Postecoglou was supportive of Rojas's move but expressed his disappointment at losing one of his best attackers.
"We wish Marco all the best as he continues on his very impressive football journey," Postecoglou said.
"While we would have loved to have seen him stay here at Melbourne Victory for a little longer, we knew we couldn't stand in the way of his European ambitions.
"He's rightly attracted plenty of attention around the globe for his efforts this year.
"He's obviously a very talented young man and has been rewarded for his stellar efforts this season by winning the prestigious Johnny Warren Medal and the NAB Young Footballer of the Year, the first A-League player to win both those awards in the one season."
