Former goalkeeper David Seaman has suggested that Arsenal cannot afford to have a quiet summer transfer window.

The Gunners will spend a third season out of the Champions League, after the club followed a fifth-place finish in the Premier League with a 4-1 defeat to Chelsea in the Europa League final.

Unai Emery is set to be handed a limited budget, but Seaman has called on owner Stan Kroenke to spend big in order to prevent the club from falling further behind their rivals.

Seaman told football.london: "Give him some money. Give him a transfer window. There have been two transfer windows that have gone by and he's had nothing.

"The board need to back him or otherwise we are going to be left further behind."

Emery has admitted that he may have to make several changes to his first-team squad this summer.
