If he had joined the Saudi Arabian club, he would have become the highest-paid footballer in the world.
In an interview with TalkTV, he said he was happy at Manchester United.
The Portugal forward was offered a two-year deal by Al- Hilal.
When asked if the rumour was true, he said it was.
The garbage that nobody wants me is completely incorrect.
I wanted to do a great season here and I was happy to be here. The media keeps repeating that nobody would want him. They don't want a player who scored 32 goals in a year.
It's hard, it's difficult, when you turn down money. I thought that I was still capable of scoring goals and that I was very happy here.
I still believe that I can score many, many goals and help the team because I believe that I'm still good and capable of helping the national team. It's difficult if you don't feel like you're on top of things.
The criticism is going to be that he's 37 and not the same. I want to see if some of my friends can keep up with me. In this moment, I'm very happy. I think I'm going to do an amazing World Cup and I'm ready for it.
Following his interview with Morgan, in which he said he felt betrayed by United, he was forced out of the club.
He has no plans to stop playing despite his former team-mate Gary Neville saying that United have to end his contract.
"I want to play at least two more years," said the player. Two or three years max. I would like to end with 40. 40 will be a good age according to me.
I don't know what's going to happen. The life is dynamic when you plan one thing for your life. You don't know what will happen.
