Arsenal fans clashed with eachother over jeering Shkodran Mustafi during defeat to Lyon yesterday.
The German came off the bench on 70 minutes and was met with loud boos from the home fans as he made his way onto the pitch.
Mustafi's brief cameo showed some Gunners fans had no time for the German and clearly want him out the club.
But this angered many fans on social media who thought it was unacceptable to boo one of their own.
I’m the first person to want Mustafi to leave Arsenal, but while he’s at my club I’ll support him. I have never booed and player and never will. I hate the idea of fans booing their own players so much — Steph (@stephpgold) July 16, 2019
