Ferguson has told his money men to get the Argentine striker and a delegation has gone to South America to get to the bottom of how exactly United can buy the controversial star.
Tevez is playing for his country in the Copa America, but his club future is being decided in talks between United and his handlers - plus former Brazilian club Corinthians.
United hope to sign Tevez for around £20m, but will go higher if necessary. They want to make the Argie a 'clean' signing, without anymore third party interests.
