Arsenal’s Carabao Cup hopes were dashed at St. James’ Park, with Isak playing a key role in their 2-0 defeat (4-0 on aggregate).
The Magpies advanced to another final, having beaten the Gunners by the same scoreline in both legs.
Post-game, Arteta said: "I’m not here to evaluate opposition players but it’s clear that he had two actions to finish and you know what happened."
Pundit Gary Neville said: "It’s all about Isak. He is messing the Arsenal centre-backs about. Look at him against Saliba, he (Saliba) thinks he has got in front and he pops it round the corner.
“What a strike it is, and a piece of good fortune because the pass isn’t into him and it then falls to Murphy. But he has Gabriel and Saliba on toast."
