Falcao promises goals
Falcao says he is ready to fire United up the league after a difficult few days.
"For me it is amazing," he told the Observer when asked about his move to United.
"I am very happy. I hope to give my team the best and help to bring a lot of goals and victories.
"I think I have lived this week very intensely. It hasn't been the most comfortable week to work in, with all of the changes, but I have lived it like a kid.
"I have had the same feeling as when I debuted for the national team. It was very exciting and special and I enjoyed being back."
Falcao came off the bench late on in his country's 1-0 defeat to Brazil on Friday in Miami, and he is understood to be applying for a fast-track visa to be able to face QPR on September 14.
"I now leave in a very good condition to join my club and I hope to be available next week,” he added. "I go to Manchester with lots of hopes to try to win a place in the team and then come back to play for Colombia. It's better to not overthink and let things happen normally instead."
