Arsenal battered Bournemouth 5-1 to maintain their place in the top four as the race for Champions League qualification intensifies.
Emery handed playmaker Ozil his second start in less than a week as he continues his comeback to the Gunners first team.
And the German duly delivered, taking just four minutes to open the scoring.
Ozil, 30, has largely struggled to gain Emery’s trust since the Spaniard’s arrival at Emirates Stadium and was linked with a move away during the January transfer window.
But the ex-Real Madrid man impressed his head coach with a mix of guile and graft against the outclassed the Cherries, stating a convincing case for selection in this weekend’s north London derby.
“Good,” Emery responded when asked by the BBC about Ozil’s performance.
“I think he’s happier with us. I am now also very proud of players and the same with Mesut.
“He helped us with his quality and his work also to organise and play in different systems.”
