And Merson, who played for Arsenal between 1985 and 1997, is baffled by Emery for not playing Ozil more often.
The German has struggled to earn his place in Emery's setup in recent weeks, with a combination of injuries, illness and the Spaniard's tactical plans resulting in Ozil falling out of favour at the Emirates.
"He must sit there and think he might as well retire if he can't get into Arsenal team".
Although he only has three goals and an assist to his name, Merson reiterated that Arsenal #10 is still their best player and should not be kept out of crucial games. 'He's there best player and he doesn't play...
"He must sit at home and watch Arsenal and think 'how am I not getting into this team?'"
'To let player contracts run out in this day and age for how much these players go for and how much they're worth is criminal.
"Ozil is not so influential that you have to build a team around him, but he has to play because he is their best player".
'Maybe you have to bring out another attacking player and put another defensive midfield player in.
The Gunners were beaten 1-0 by BATE Borisov, but the players believe they could accommodate Ozil, who has fallen down the pecking order at an alarming rate this season, as he faces an escalating predicament. Sometimes it doesn't work out, but you have to stick with him.
The young French midfielder made his first team debut at French second-tier club Lorient before moving to Arsenal at the start of the season.
