Newcastle United legend Alan Shearer was impressed by Arsenal midfielder Lucas Torreira for Saturday's win.
Shearer admitted the midfielder was the difference between the two sides on the day.
"They (Arsenal) certainly deserved the win, they were much the better team in the second half," Shearer said on the BBC's Match of the Day.
"Torreira made a difference when he came on at half-time.
“The difference that was he looked forward so quickly.
"Every time he got the ball his first thought was 'Can I move it forward?' and there was so much more movement ahead of him where there wasn't in the first half.
"That was the big difference."
