The Arsenal Supporters' Trust fears that Arsene Wenger's 'obsession' with developing youth players is damaging the clubs ambition and ability to win silverware.
And it has been revealed that the manager has got about £70million to spend this summer but have failed to recruit any big-name stars - only France under-20 free agent Yay Sanogo has walked in the Emirates stadium.
Having already missed out on Gonzalo Higuain, Wayne Rooney and Luis Suarez, it is understood that Newcastle have today rejected a £10million bid for midfielder Yohan Cabaye, adding to the sense of frustration.
Tim Payton, a spokesman for the AST said: "For now the club's entire focus must be on using the remaining days of the transfer window to strengthen the team significantly.
"We don't know whats going on but clearly there's a manager that by his own words isn't a big fan of spending money on strengthening the team through expensive player acquisitions.
"His apparent obsession with being a developmental manager is in danger of holding the club back.
Payton added: "Arsenal fans pay some of the highest ticket prices in world football and we want to see that invested in top players."
The Gunners were booed off after Saturday's 3-1 home defeat against Aston Villa and a lengthy injury list, which now includes Alex Oxlade-Chamberlain, is set to give Wenger a headache with a crucial Champions League qualifier against Fenerbahce on Wednesday night.
Mikel Arteta, Nacho Monreal and captain Thomas Vermaelen are all ruled out for several weeks.
