Radamel Falcao says he wants to play for Manchester United ''for many years'' after joining on a season-long loan from Monaco. United is the Colombia striker's fifth club in as many years, having left River Plate in 2009 to join FC Porto before moving to Atletico Madrid two years later. For Falcao, those teams were stepping stones ahead of a move to a major European club like United. Falcao, who was presented as a United player on Thursday, says ''when I was in Porto, Atletico Madrid, I always wanted to improve and dream of playing in a team like this, and now I want to stay here for many years.'' United has the option of signing Falcao - for a reported 44 million pounds ($71 million) - next year.
