Three thoughts from Manchester United's 5-1 triumph over FC Midtjylland on Thursday to earn a place in the Europa League last 16. Manchester United have a new hero, while manager Louis van Gaal rides on. Marcus Rashford, a name previously familiar only to the aficionado of United's youth teams, grabbed a pair of second-half goals that saved his manager from the deep embarrassment of exiting the Europa League at the hands of minnows. The knives that were being sharpened for the Dutch manager can be placed back in the drawer . Rashford, 18, replaced Anthony Martial who pulled up in the warm up as Pione Sisto put the Danes ahead before an own goal from Nikolay Bodurov levelled it up on the night. Juan Mata missed a penalty but Rashford scored twice in 15 second-half minutes to send the Red Devils through and give Louis van Gaal a stay of execution.
