In just his third match in charge of Manchester United, Louis van Gaal oversaw one of the most humiliating losses in the club's illustrious history on Tuesday.

The record 20-time English champion timidly capitulated to MK Dons, losing 4-0 to the third-tier club in the second round of the League Cup.

Hired to halt the decline under David Moyes in the post-Alex Ferguson era, van Gaal had already endured a loss and a draw in his first two Premier League matches before one of three possible routes to silverware ended in Milton Keynes.
