And some Arsenal fans are not happy the Gunners conceded to the UAE minnows.
Arsenal are in the UAE on a warm-weather training camp during this international break.
Unai Emery was able to name a strong side for the friendly today, with Alexandre Lacazette and Mesut Ozil both starting.
But Arsenal endured a miserable start to the friendly game after Ronnie Fernandez fired the hosts in front.
It was a stunning goal from the Chilean on the edge of the box.
But Arenal fans were not happy Fernandez was allowed time to control and shoot in off the post.
And their ire was directed specifically at Shkodran Mustafi.
One fan tweeted: “Deserved goal for Al-Nasr! Very sloppy start from Arsenal”
Another said: “Arsenal are playing against a team from Dubai and still Mustafi is at fault for the goal? How’s he still playing”
A third said: “It’s International break yet we’re still conceding goals. Only Arsenal.”
And a fourth sarcastically tweeted: “Mustafi with some world class defending there on the al Nasr goal.”
Nigel Winterburn was commentating on the game for Arsenal TV and said: “No goalkeeper in the world is going to save that.
“First it was a fantastic touch.
“And second to curl it in off the post.”
Arsenal did eventually get level in the friendly when Carl Jenkinson scrambled home a rebound after hitting the post.
