That is according to former Arsenal striker and Sky Sports pundit Charlie Nicholas, who has admitted that the Gunners need a whole new defence for next season.
Emery is rumoured to have just £40m to spend this summer after the club missed out on qualification for the Champions League last season.
This means the club has to be shrewd in identifying their transfer targets this summer.
Emery will be hoping that more funds can be accumulated through selling some players also.
Nicholas is disappointed not to see any new signings yet though the door at Arsenal but says defence is the area that needs addressing.
He claims right-back Hector Bellerin, who is recuperating from a serious knee injury, is the only defender at the club he would keep in his back four.
“My club Arsenal is slow again in the market, I don’t like the way they’re going about it,” Nicholas told Sky Sports News.
“I think the manager has identified plenty of options, mainly defensive structure which is the key area.
“My club Arsenal is slow again in the market, I don’t like the way they’re going about it”
“I think there has been little change in policy in terms of toing and froing.
“Stevie Bould I think is moving back to the Under-23s, Freddie Ljungberg’s getting promoted, there’s been little changes here and there.
“But the signs are they’re actively looking in the market. But I just hope Arsenal don’t to and fro and delay these processes.
“They’re talking about a lot of good, young defenders that they’re interested in. Arsenal need to start getting into the market.
“I’m seeing now about [Aaron] Wan-Bissaka for £50million to Manchester United – Arsenal can’t afford that, we don’t have the finances.
“We need a whole new defence, and I mean the back four. Probably if Bellerin fit then that’s fine.
“We’ve got a couple of young players to come back, Rob Holding being one of them.
“But that will be squad-orientated, we probably need three main defenders to come in.
“That’s going to cost the best part of £60m or £70m.”
