Arsenal fans question Arsene Wenger's future as manager Arsene Wenger should not be offered a new contract as Arsenal boss, according to the Arsenal Supporters' Trust (AST). The Gunners have not spent any money in the transfer window and lost 3-1 at home to Aston Villa on the opening day. Chief executive Ivan Gazidis has spoken of the intent to offer Wenger a new contract. We believe this is inappropriate," read an AST statement. The entire focus must be on using the remaining days of the transfer window to strengthen the team significantly. Arsenal have qualified for the Champions League in each of the past 16 campaigns but their most recent trophy success was the 2005 FA Cup. After securing fourth place in the Premier League on the final day of last season, Gazidis revealed the board was ready to spend big after an "escalation in our financial firepower" created by new television and sponsorship deals. But Arsenal's only summer signing to date is the 20-year-old French striker Yaya Sanogo on a free transfer from Ligue 1 side Auxerre, with numerous players leaving the Emirates Stadium. The AST has called on the club to invest some of their available money - they have a reported cash balance of £154m, which is almost as much as the rest of the other 19 clubs in the Premier League combined. "Ambitious football clubs invest the money they receive from their fans, and sometimes their owners, to make themselves stronger," said the AST. Arsenal supporters pay some of the highest ticket prices in world football, providing the club with considerable financial resources, but the ambition and ability to use them appear to be missing. The fact that there is money available for squad-strengthening is not disputed. The AST's independent analysis suggests that the amount is somewhere between £70m-£100m. It also wants American owner Stan Kroenke to take decisive action. "Stan Kroenke does not attend many Arsenal matches nor seem to have the time to devote to the affairs of Arsenal," the statement continued. But it is clear to all that football personnel he is ultimately responsible for are failing. The AST calls on him to appoint an independent expert to conduct a review of all football functions at Arsenal. Clearly the interaction between our scouting, negotiating and player purchasing processes are failing and need urgent improvement. A decision on whether to offer an extension to the manager's contract, which ends in May 2014, should only be taken following the closing of the transfer window and assessment of the team's performances. Considerable improvement must be shown for us to be convinced this should happen.
