Arsenal's season hit a new low midweek when they were knocked out of the Capital One Cup by League Two Bradford.
Reports surfaced that there are problems in the working relationship between Wenger and his backroom staff.
But Wenger said: "We are a united staff team. We cannot control lies which are written.
"What is important for us now is the future, how we do in the Premier League, the Champions League and FA Cup, not whether we are out of the Capital One Cup or not.
"We all look to the future.
"I believe we have a strong squad and it is up to them to show I am right."
Wenger hopes Arsenal will provide the required response when they head to struggling Reading on Monday night, aiming to close back up on the top four of the Premier League.
"I believe it's a good opportunity to show that we are strong inside the club and let people talk," said Wenger.
"We are criticised when our results are not good, we have to take that on the chin. That we have to face a lot of lies is less acceptable."
Wenger added: "We are top professional people. What is important is what happens tomorrow, not what happened yesterday.
"We are sorry for that [the Bradford loss], but what is important is the next game. The squad should just focus on the next game."
