"Neither the club or the coach have said anything about that (leaving Manchester United), I think it was a rumour that came about in Ecuador more than anywhere else," the Ecuadorian ace told Radio La Deportiva.
"This [Manchester] is my home, I would like to stay here for a lot longer and retire here before going back to Ecuador."
"When I had the problem with my leg I recovered mentally without any difficulty," he said.
"But the problem with my back was something that affected me for a lot longer, but now I am fine and physically much better."
The 27 year old was talking after helping United to clinch the Premier League title on Monday against Aston Villa.
"I am very happy, this is my second championship here," he said.
"I have the confidence that the coach has given me and when you go into a match with the confidence of the team, it gives you extra motivation."
