That’s the view of pundit Mark Lawrenson, who is predicting the Gunners to get their first win of the season against West Ham today (3pm).
Emery took over at the Emirates following the departure of Arsene Wenger after 22 years in charge of Arsenal.
His Premier League start wasn’t the easiest with champions Manchester City beating the north London side 2-0 before a 3-2 defeat to Chelsealast weekend.
Emery has already come under fire for his tactics, with the Spaniard preferring his team to play out from the back.
At times, it has put Arsenal under pressure through sloppy passes and poor touches.
But Lawrenson believes Emery should be given time to see his tactics bear fruit and insists he can succeed.
“I am almost thinking that for this season – as new manager Unai Emery gets his feet under the table and imposes his style – Arsenal should not put pressure on themselves to finish in the top four,” Lawrenson wrote in his BBC predictions column.
“They need to develop and, after more than 20 years with the same manager, it is always going to be difficult.
“They are trying to play out a little more from the back and all it needs is for one player not to be comfortable doing so for it to be a problem.
“If Emery wants to play that way he will have to suffer one or two defeats along the way, but I think ultimately he will get there, partly because he will get the personnel in who can fit that style.”
Arsenal stars Granit Xhaka and Mesut Ozil have both felt the force of Emery already having been substituted during the opening games.
Their opening two defeats represent the Gunners’ worst ever start to a campaign since the Premier League began in 1992.
And Ian Wright, who played for the club in Wenger’s first two of 22 seasons in north London, praised Emery’s different way of thinking.
“I think the other day rightly at half-time, which you may not have seen under Arsene Wenger, he [Xhaka] got taken off,” Wright said.
“He’s frightening me at the moment if it [the ball] goes to him because his confident seems shot.
“What was good and encouraging was that he made those substitutions, big substitutions for me.
“Xhaka would have stayed on under Wenger and so would Ozil.
“And what that’s said now in that dressing is that no one’s going to be safe. ‘If you don’t do what we need you to do, you’re coming off’. And I was pleased to see that.”
