The Frenchman following a 2-2 draw with Southampton indicated that the Gunners could make a move before deadline day.
When asked by reporters whether to expect any arrivals before the transfer deadline, the Frenchman replied: "I hope we have something to tell you."
The 64-year-old was speaking after the club's 2-2 draw with Southampton, a result that could see the Gunners slip to third place in the Premier League should Manchester City and Chelsea win Wednesday.
However, Wenger was still satisfied with a point in a hard-fought game which, at one stage, they looked like Arsenal could lose.
"They have difficult games as well and we took at least a point," he said. "It's not enough but considering the situation at halftime [Arsenal was 1-0 down], we have to be content with it.
"I don't want to look for any excuses: They played at higher pace. In the first half we didn't play well. In the second half it was a very good football game. We've shown character and resilience."
There was more bad news for the north London club as returning midfielder Aaron Ramsey reportedly suffered a new thigh injury that could keep him out for another six weeks.
