Thierry Henry has blasted a Manchester United player for his reaction after Harvey Barnes' second goal on Sunday.
Meanwhile, Jamie Carragher claimed the team's defending would be 'unacceptable' in primary school in a brutal broadside against Ruben Amorim's men.
Barnes forced Noussair Mazraoui into a mistake mid-way into United's half to claim the ball and beat three defenders to fire past Altay Bayindir in Newcastle's 4-1 demolition job.
Leny Yoro, one of the men Barnes left in the dust, immediately looked over at the linesman - despite there being no hint of a foul or offside in the build-up.
