Louis van Gaal's miserable start to life as Manchester United boss continued with a massive Capital One Cup shock at the hands of League One MK Dons.

Playing in the second round for the first time in 19 years, United were mauled by an energetic and clinical performance from the side two divisions below them, who were playing in front of a crowd of 26,969 – the biggest in their 10-year history.

Four-time winners United did not register a shot on target until the 72nd minute against the team who were only founded in 2004.

Will Grigg scored after a Jonny Evans mistake and then chested in an audacious second after the break.

Benik Afobe, on loan from Arsenal, added two of his own to complete an embarrassing rout for the Premier League giants.
