The Spanish coach took over the reins from Wenger in the summer after the 69-year-old parted company with Arsenal after 22 seasons in charge of the Premier League club.
Wenger led Arsenal to three Premier League titles and seven FA Cup crowns during his decorated spell in charge, but the Frenchman failed to secure a Champions League spot in his final two seasons.
Emery signed five new players in the summer transfer window to revamp the Gunners squad, with Uruguay international Lucas Torreira impressing in the middle of the park.
Arsenal bounced back from successive losses to top-six rivals Manchester City and Chelsea FC at the start of the season to go unbeaten in 14 games in the Premier League.
The Gunners saw their run come to an end last weekend following a 3-2 loss at Southampton before a 2-0 defeat by Tottenham Hotspur in the League Cup quarter-finals mid-week.
However, Arsenal returned to winning ways with a 3-1 win against Burnley on Saturday afternoon.
Former Arsenal manager Wenger has been impressed with how Emery has managed to improve the Gunners defence over the past few months.
“I think Emery is doing an excellent job,’ Wenger told beIN SPORTS.
“With the recruits he has brought in, it has brought a form of defensive stability and so I think everything is going well.
“The team is in good hands and I always said that. A lot of people thought when I left the club that the team would need to completely rebuild – I never thought that.
“I am very happy that these people have been proven wrong.”
Arsenal lost 2-0 to Spurs in the Carabao Cup last eight but the Gunners are still in the Europa League after coasting through the group stage.
Emery has won the Europa League three times during his spell at Sevilla.
