The club have been attempting to keep the new strip under wraps and had originally planned the launch to come just ahead of their North America tour this month but Manchester United allowed the reserve team to wear the new kit two days ahead of its scheduled release.
The new kit is a plain red number with a white fly-away collar, much like the kit worn by Bryan Robson and co in the early 1980s and features the logo of new sponsor Aon.
United agreed a four-year deal with Aon Corp, the American financial company, thought to be worth £80million back in 2009.
