Dawson repeatedly called for his players to keep their shape and manage the game, but Henderson's presence behind Leo allowed the young midfielder to continue pressing forward without leaving the centre completely exposed.
When Wigan recovered possession, Leo remained one of their first outlets, demanding the ball and looking for the next pass rather than forcing a run every time.
Through it all, United struggled to even get an inch of the pitch.
Their attempts to move the ball forward became increasingly hurried, and the distance between their midfield and defence grew whenever they committed players to the attack.
Wigan were happy to let them come, then close the available passing lanes and break into the spaces they left behind.
The home side didn't need to chase the game; United were doing enough of that themselves.
Still, the visitors managed to find the net in the seventy-seventh minute.
