Arsenal manager Arsene Wenger will spend between £100m and £120m during the summer transfer window, former striker John Hartson believes.
The Gunners have already secured the services of Switzerland international Granit Xhaka for £34million but are expected to sign at least two more world class players before the end of the market.
And the Welshman believes Gonzalo Higuain, Jamie Vardy or Alvaro Morata would be excellent signings for the Gunners.
"They've just gone out and bought a good player in Xhaka," Hartson told Metro.
"They needed a holding central midfielder and they've paid around £30m for him, which is the type of money the Arsenal fans want to see being spent on the best players.
"I think Arsene Wenger will spend a lot of money this summer. I expect him to spend between £100m and £120m and I think they'll have a real challenge next season.
"He's been holding that money back slightly and been a bit cautious to go and spend it.
"But after finishing second behind Leicester, the fans will want the title next season and I think he'll bring in some seriously good players this summer.
"They need a centre-forward and a centre-half.
"Arsene Wenger has to buy players who can take them forward and enhance the team.
"Alvaro Morata would be a good signing.
"Robert Lewandowski is another one. I think the other one would be Napoli striker Gonzalo Higuain.
"You've got Jamie Vardy and one or two others in the Premier League that could be worth a shout too.
"Arsenal need to be in the market for these kinds of strikers this month."
