Arsene Wenger claims his Arsenal squad is missing one more player, something he will aim to address during the January transfer window.

The Gunners brought five players to the club in the summer but cash reserves of £173.3m –as revealed in the release of the club's financial records in September – raised questions as to why the club's spending stopped there.

An unrelenting spate of injuries that has decimated the squad has further raised concerns over the strength in depth at the Emirates.

Speaking at Arsenal's Annual General Meeting, Wenger said: "We bought four [outfield] players. Two defenders in Chambers and Debuchy and Sanchez and Welbeck. We've done remarkably well in the transfer market.

"I agree we could have bought another player. We will try and rectify that in December ahead of the transfer market in January."

The subject of Arsenal's exorbitant cash reserves raised the question as to whether Wenger had been given the financial backing to match the Gunners' rivals in the transfer market. That was a notion strenuously denied by chief executive Ivan Gazidis.

"There is inaccurate analysis about cash available," Gazidis said. We are not hoarding a vast cash balance. We do not try to broadcast our cash situation but situation is more complex.

"We do try to keep a reasonable amount for the transfer budget. It is quite untrue that we are sitting on a huge cash pile for some unspecified reason."

Arsenal chairman Sir Chips Keswick and majority shareholder Stan Kroenke were also present at the AGM answering questions raised by the Arsenal Supporters' Trust and others.

Amid issues of a payment of £3m paid to Kroenke Sports Enterprises, the troublesome issues of ticket pricing and the club's transfer activity, the Gunners' board was also quizzed on the long-term future of the club in the post-Wenger era, despite the manager signing a new deal earlier this year.

Keswick was reluctant to discuss the club's plan when asked whether they had learned from the mistakes made by Manchester United in naming Sir Alex Ferguson's successor. He did however suggest Arsenal would "be spoiled for choice" when the Premier League's longest-serving manager does decide to step down.

"I don't comment about other clubs - good luck to them and their problems. It's premature to speculate about the successor to Arsene. I'm delighted he has signed a three-year contract. Rest assured we follow the situation carefully," Keswick said.

"I believe this great club will always be attractive for the great managers. I hope when the time comes we will be spoiled for choice. It's not being complacent - we think about it all the time - I hope when the time comes we will have a solution that pleases you."
