Manchester United will sack Louis van Gaal is they're beaten by FA Cup opponents Shrewsbury Town on Monday.

The Daily Star Sunday says even staff at the club believe the manager's position would be untenable if United lose at Shrewsbury in the FA Cup on Monday night.

And a double failure this week, with a European exit if United flop again against Midtjylland on Thursday night, would embarrass executive vice-chairman Ed Woodward as well as Van Gaal.

United are already set to have one of their lowest attendances in recent times for the Europa League tie with the fans on the brink of revolt.
