Manchester United beat Shrewsbury by an unexpectedly easy 3-0 in the fifth round of the FA Cup on Monday and gave manager Louis van Gaal at least three days' breathing space.
On Thursday, United has a must-win Europa League match against unheralded Danish side FC Midtjylland.
In the FA Cup, United will host West Ham in the quarter-finals in three weeks.
At the New Meadow, in front of almost 10,000 fans, the 11-time FA cup winners never looked in danger against Shrewsbury, the lowest-ranked team left in the cup.
Chris Smalling, Juan Mata, and Jesse Lingard scored.
