Arsenal legend Lee Dixon believes the club must improve every aspect of their team.
The Gunners face a tough offseason having missed out on a UEFA Champions League position for next season.
It means boss Unai Emery has a limited transfer budget with which to improve on a team that finished fifth in the Premier League.
And Dixon believes his task is a difficult one, as he must improve in every area of the squad.
Dixon told talkSPORT: "It's a huge summer for Arsenal. It was always going to be a big summer regardless of where they finished and whether they got to the Europa League or not.
"I think Emery knew this season was going to end like this, to a point where we either got into the top four and got Champions League football or we didn't quite. We failed on that front.
"So he's got to look accordingly, and try to convince the board and powers that be to give him enough money to improve the squad.
"It does need improving in all departments, and lets hope we can keep hold of our best players in order to do that."
