Liverpool star: We could hear Man United players shouting at each other at half time

Liverpool defender Mamadou Sakho says his team-

mates heard their United counterparts tearing into

each other at half time.

The game was goalless at the break but a Wayne

Rooney strike off a rebound in the second half earned

the Red Devils a 1-0 victory .

And Sakho says Louis van Gaal's men didn't deserve

their triumph at Anfield.

"United were lucky today and they know it," Sakho told

French TV station Canal+.

"We could hear them shouting in the dressing room at

half time.
