Mikel Arteta has urged owner Stan Kroenke to provide funds for his Arsenal rebuild to avoid him having to weaken the squad if he is forced to sell to buy.
Arsenal are facing a first season without European football since 1995-96 and are set for a big financial hit, hampering their possibilities in the transfer market.
They already have strengthening in central midfield, the left side of their attack and at left-back among their summer plans.
And there could be further reinforcements required depending on who leaves.
Arsenal are resigned to losing right-back Hector Bellerin this summer, while strikers Alexandre Lacazette and Eddie Nketiah are facing uncertain futures along with those out on loan such as Matteo Guendouzi, Lucas Torreira, Joe Willock and Ainsley Maitland-Niles.
