However, the German put in one of his best performances of the season against the Magpies, getting on the scoresheet during a 4-0 win.
While Keown has not shied away from criticising Ozil in the past, the former centre-back was full of praise for him after his display at the weekend.
Speaking to BBC Sport, Keown said: "Ozil, I thought his movement was really important, there was running off the ball with [Pierre-Emerick] Aubameyang and [Nicolas] Pepe was told that in the second half he needs to get at his opponent, which he didn't do in the first half.
"Ozil was magnificent and [Bukayo] Saka just keeps getting better and better. Ozil had much more purpose in his play and he gets his reward, fortunate with the finish but he deserved that goal.
"He's playing centrally, he wants to be that player who threads things together and it's really going well for him."
Ozil's goal was his first of the season, adding to just two assists in all competitions. body check tags ::
