C. Ronaldo has said he could stay at Man U for the next “three or four years”.
According to him, he has returned to the club to “win again”.
Ronaldo returned to United after 12 years on a two-year deal with the option for one more.
The Portugal captain was interviewed by former team-mate Wes Brown on MUTV ahead of his potential second debut against Newcastle on Saturday.
Ronaldo said: “I am not here for a vacation. As I told you, before was good, winning important things and I wore the shirt before many years ago, but I am here to win again.
“I am capable, me and my team-mates. It is a good chance for me, for the supporters, for the club.
“I am ready and I think I will be a huge thing in the next three or four years.”
