That is according to BBC Sport reporter David Ornstein.
Sven Mislintat leaves his position as head of recruitment on Friday after a reported difference in vision with director of football Raul Sanllehi.
Mislintat held the same post at Borussia Dortmund, where thrifty singings such as Robert Lewandowski, Pierre-Emerick Aubameyang and Shinji Kagawa became revelations in the Bundesliga.
The German announced his departure during the transfer window, in which Arsenal claimed they could sign players on loan, leaving the transfer policy of the club in doubt.
The search for his successor has already begun with Roma equivalent Monchi fancied, but despite the uncertainty the Gunners are still expected to leverage a relatively hefty budget for the coming summer window.
Amid the current flux at Arsenal, Ornstein told the Arseblog podcast: “Arsenal, when you speak to them, are very calm. They see this as a project.
“I was told [a year ago] that 2019/20 was going to be when Arsenal were hoping to be competitive again. I was told it would take three, four, five transfer windows – they were very realistic, Emery was a long-term appointment.”
After losing his first two league games, Emery spearheaded the Gunners to a 22-game unbeaten run in all competitions which exceeded the expectations set by the board and most fans.
That may have inadvertently hurt the Spanish coach’s project, though, Ornstein explained.
“Perhaps that 22-match unbeaten run was a bit of curse to him because it seems that many expectations have changed and suddenly people are questioning his suitability to the position,” the journalist said.
“Of course, he’s not immune to questions on the pitch, some tactical decisions. There are some things that clearly haven’t been done right as he tries to explore and find his team balance.
“But I think people need to relax a little bit and see how this plays out, rather than jumping to conclusions on the immediate term.
“I’m not a sympathiser of [Arsenal owners] the Kroenkes – I know many people who have a very dim view of them inside and outside Arsenal and within the game.
“The proof is going to be in the pudding in the next year or two. For instance, why was there no money to spend in the January transfer window?
“Well, we know Arsenal spent heavily in the previous two transfer windows, we know they have revenue streams coming on in terms of [the] Adidas [kit deal] in the summer, there’s various talks about stadium refinancing.”
Although the precise transfer strategy heading into July is unknown, Ornstein went on to reveal there are rumours of a nine-figure warchest.
“The truth is we don’t know exactly why there was no money to spend – it hasn’t been communicated properly, either publicly or in private,” he added.
“We don’t know the precise sums – I’ve been told it could be £100million in the summer. We’ve been told that in the past and we don’t want to either excite or disappoint people.
“It seems a shame, a real shame, that just when it appeared that Arsenal were building in the right direction over the last year, they managed to encounter problems behind the scenes with the Mislintat situation, with the contractual problems around Mesut Ozil, Aaron Ramsey.
“They’ve got to ship some players out in the summer – I think they will do so. I think Sanllehi is quite a ruthless competitor.
“But it is a shame that that aim of being competitive from the start of the 2019/20 season seems like it suddenly has been derailed somewhat.
“That said, I think Emery is an appointment who the club are fully behind and will work together with him to get things right.”
