Arsenal must be willing to invest greater funds into the playing squad to avoid falling behind their Premier League rivals, says David Seaman.

A fifth-place finish in the top flight means Arsenal will miss out on Champions League football for the first time in 19 seasons, with manager Arsene Wenger’s future still undefined, despite his contract expiring next month.

There was further turmoil this week with reports that Alisher Usmanov, owner of 30 percent of Arsenal’s shares, was seeking to purchase Stan Kroenke’s 67 percent majority stake for £1-billion, but the American’s company, KSE UK, stressed on Monday that its shares were not for sale.

Regardless of what happens at Emirates Stadium during the close season, Seaman – a three-time Premier League winner with Arsenal – wants to see a greater willingness to spend big to avoid being priced out of major signings by other elite clubs.

He told Omnisport: “All that concerns me, whatever happens, is I want for there to be more money available for the manager.

“I think we are getting left behind a little bit by two or three clubs that are now ahead financially and they are spending money and things need to change at Arsenal.

“They need to look at their wage structure – how can you attract the top players when you’re not paying the top money? It is as simple as that.

“They have got to be real with what’s being paid to players. If you have a top player who wants to come to London and at Arsenal, he is being offered to say 100 grand and at another club, it’s 200 grand, where is he going to go?

“For me, it’s as simple as that – we are not attracting big players anymore.”
