The spokesman for the group reveals that the Frenchman will have plenty of resources available to him in the window as the Gunners seek Champions League qualification.
Arsenal qualified for the last 16 of the Champions League with considerable ease, but the club's quest to end a seven-year trophy drought came crashing down at Valley Parade as League Two Bradford City eliminated the team with a dramatic 3-2 penalty shootout win in the Capital One Cup.
The AST met with chief executive Ivan Gazidis on Wednesday to discuss the club's perceived lack of direction, but the group was assured that the Frenchman will be given the financial backing required to compete.
"There is plenty of money there," Trust spokesman Tim Payton told BBC Sport. "That was the message that Ivan and his finance director were giving this evening. He stayed for over two hours. He apologized for the result [at Bradford] and said it was not good enough and had to be better.
"The Arsenal fans were dissatisfied with the strength of the squad and particularly don't understand whether there were resources to be used. I specifically raised this with the finance director and his colleague and they were in no doubt there is considerable resources available to the manager ready to spend when he has identified the players he wants to sign. It's crystal clear that Arsenal fans need to wait until January for Arsene Wenger to use the check book he has been given well."
Wenger's position has come under increasing scrutiny in light on recent results, but the Trust still has complete faith in the club's most successful ever manager.
"Lots of people have asked me whether Arsene Wenger should go," said Payton. "He certainly needs to change and improve, spend the money he's got, strengthen the set-up around him and the results will be the judge."
