United will play five games in July, starting with a fixture against New England Revolution on Wednesday. Ferguson's side will also face an MLS All-Stars side which will include David Beckham, and Barcelona.
And as our pictures show, United's top players have all been included in the tour party and will be aiming to impress the boss over the coming weeks.

The party posed on the steps of their plane and judging by the size of their hand luggage, this was no easyJet flight.
The ever-green Ryan Giggs seemed relaxed at the airport after a troubled summer of tabloid revelations.
He posed for pictures with fans and appeared to share a joke with airport staff.
It is unclear if the Welshman's good mood was directly related to the recent closure of the News of the World.
Wayne Rooney meanwhile looks to be recovering well from his hair transplant as he showed off his new barnet.
His teammates Ashley Young and Rio Ferdinand appear to me lending him morale support by sporting matching skinheads.
Strikers Dimitar Berbatov, who looks set to remain at the club despite being dropped for the Champions League final, and Michael Owen, who signed a new one-year deal, will be hoping to prove their worth in pre-season.
Manager Ferguson also appeared to be in a jovial mood; but that will surely change as soon as his side is the victim of a dodgy refereeing decision.
