Rooney has released a statement on Wednesday evening in response to Sir Alex Ferguson's comments on Tuesday. And in it, he confirms he wants to leave Old Trafford.
"I met with (chief executive) David Gill last week and he did not give me any of the assurances I was seeking about the future squad," said Rooney.
"I then told him that I would not be signing a new contract."
Rooney admitted he was surprised by the depth of Ferguson's comments yesterday.
He remains a big fan of the United boss but says the future direction of the club was causing him concern.
"I was interested to hear what Sir Alex had to say yesterday and surprised by some of it," continued Rooney.
"It is absolutely true, as he said, that my agent and I have had a number of meetings with the club about a new contract. During those meetings in August I asked for assurances about the continued ability of the club to attract the top players in the world.
"I have never had anything but complete respect for MUFC. How could I not have done given its fantastic history and especially the last six years in which I have been lucky to play a part?
"For me its all about winning trophies - as the club has always done under Sir Alex. Because of that I think the questions I was asking were justified.
"Despite recent difficulties, I know I will always owe Sir Alex Ferguson a huge debt. He is a great manager and mentor who has helped and supported me from the day he signed me from Everton when I was only 18.
"For Manchester United's sake I wish he could go on forever because he's a one off and a genius."
