Former Manchester United captain Roy Keane has blasted Louis van Gaal's defence.
The Red Devils were beaten 2-1 by Arsenal in the FA Cup quarter-final on Monday night and Keane suggests the defending at Old Trafford from the home side was a 'disgrace'.
"It's absolutely disgraceful. Schoolboy errors and that's what costs your team," said Keane on BBC.
"Big moments in a football match and if you give Arsenal, with the quality that they have, that type of freedom that's what happens. It was too easy, shocking. Absolutely disgraceful."
The ex-United skipper added: "I think Arsenal deserved it when you consider the shocking defending from United.
"United as the home team needed to do a bit more and whatever happened at half-time, they never got going in the second half."
