The Arsenal Supporters' Trust are demanding answers after their quiet summer market.

Arsenal were the only club in Europe's top five leagues not to add an outfield player to the squad in the off-season.

"Arsenal are in a very strong financial position thanks and it is of course disappointing that the transfer window has closed with just the signing of Petr Cech," said an AST statement.

“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."

The statement continued: “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 and can only help Arsenal to become a stronger club. The AST will be raising this with the Arsenal board.

“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."
