The 27-year-old was taken off towards the end of his sides encounter with Liverpool and failed to provide an assist despite the Gunners scoring three goals.
“The player who let them down most and is getting a lot of publicity for player of the year is Ozil,” Giles told Newstalk’s Off The Ball (via Independent).
“He was the one who had the talent to get hold of the ball and do what needed to be done. He needed to take the pressure of Arsenal. Ozil was actually taking off and put on the bench.
“If he is footballer of the year this year, I’m a Dutchman. When they actually needed Ozil, they really needed him at that particular time, he wasn’t there.”
Ozil received a rating of 7 (out of 10) for his performance on the night by WhoScored. The Germany international made three key passes and took one shot on target.
The draw saw Liverpool move into 9th point meanwhile Arsenal were able to just about keep onto the number one spot on goal difference after Leicester City beat Tottenham at White Hart Lane.
Ozil has provided 16 assists and has found the back of the net twice in 26 appearances for the Gunners this season.
