Arsenal supporters were left bitterly disappointed after the transfer market window ended with the only Petr Cech signing for the club.
The Arsenal Supporters' Trust took to Twitter to demand a "full review" of how the club is scouting and signing new players.
The full statement reads as follows:
"Arsenal are in a strong financial position and it is of course disappointing that transfer window has closed with just signing of Cech.
"Arsenal have built a strong squad and just one or two more good additions would have strengthened the chances of winning a first title in 11 years
"No one wants Arsenal to buy players just for the sake of it, but we do want to see the money being invested to make the club stronger. This isn't an issue that affects just one transfer window and seems to indicate a wider structural issue
"In recent years Arsenal have overhauled both their Academy and their medical set-up. We urge the board to now open a full review into its arrangements for scouting and purchasing players.
"A review of this type is a good governance practice & can only help Arsenal to become a stronger club.
"Now that the window is closed the squad is as it is. Arsenal have a strong squad that has recently won silverware and we urge all fans to get behind the team over the rest of the season."
