Furious Roy Keane tears into Man Utd, slams Marcus Rashford

An incensed Roy Keane crucified Manchester United at the half-time break of their FA Cup quarter-final with Liverpool - just moments after the Reds took the lead.

Keane slammed United's lack of "game management" in which they failed to see out the half at 1-1 after the Red Devils took the lead at Old Trafford thanks to Scott McTominay.

The Irishman also took aim at Marcus Rashford's lack of effort, and labelled trying to play out from the back in injury time, when Liverpool were on the front foot, "criminal".

Keane said on ITV: "It's the biggest worry for United throughout this season, they are so open, particularly in midfield. They need someone to sit, it's called game management.

"We just felt Liverpool were getting stronger but United have got to get someone to sit in there and try and protect the back four, game management, to give up the chances.

"The intensity from the attacking players, Rashford, my god, you're talking an FA Cup quarter-final, get to people, attack them, it's far too easy for Liverpool, way too simple, players taking touches, get out to him.

"Just the build-up to that [the goal], not enough aggression, what happens is a lot of teams make the mistake in that we got the numbers back but it's not good having the numbers back if you're not aggressive you have got to be aggressive in his game."

On his former side trying to build an attack from the back amid intense Liverpool pressure, Keane added: "You're going to get punished but for United to play out from the back in injury time is criminal."
