Arsenal are currently adapting to life under their new manager after he was brought in as Arsene Wenger’s successor at The Emirates back in May.
The north London side have made something of a mixed start to the new campaign, winning two and losing two of their opening four Premier League games.
Emery has been tasked with steering Arsenal back into the Premier League’s top four after the Gunners finished outside of the Champions League spots for Wenger’s final two campaigns in charge.
O’Leary feels that the competition for Champions League spots is stronger than ever, and claims that finishing in the top four would be a great achievement for the Gunners.
Speaking in an interview with the Daily Express, O’Leary said: “I look at the five teams that finished ahead of us, I don’t think they’ve got any worse.
“I think it was going to be a tough job for whoever was going to come in here.
“If this manager gets into the top four, I think it’s been a great achievement.”
Arsenal will look to make it three wins in a row in the Premier League when the Gunners take on Newcastle United away from home this weekend.
The Gunners have not won the Premier League title since their famous unbeaten triumph in the 2003-04 campaign.
