Kevin Campbell has urged Arsenal to spend big on transfers this summer if they want to get back to competing for trophies.
The Gunners endured a tough 2020/21 season, struggling for consistency and eventually finishing a measly eighth in the Premier League.
Despite the club's woes they have stuck with Mikel Arteta as the manager tasked to bring them back to the Champions League, a competition they haven't played in since 2017.
Arteta faces a busy summer in terms of incoming and outgoing and football.london understands the Spaniard is hoping to bring in five new faces to the Emirates in the transfer window in a bid to improve an underperforming squad.
The Gunners will have to splash a large amount of cash to land their main targets and Campbell believes the sum will have to exceed £100 million if they are to become a top side again.
"I will be honest, I don’t know if £100 million would be enough", he told Football Insider.
"It would be nice if they could invest £500 million.
"£100 million does not get you much in the transfer market these days. If you want to sign quality £100 million would only get you two decent players.
"If you want to sign a top, top player like a Grealish you need to be spending £80 million.
"If Stan Kroenke would write a cheque for £200 million now I would take it. I think that’s how much money needs to be invested into this side to make the challengers again.
"It’s a huge summer for Arsenal."
