The Gunners manager indicated there could still be arrivals before deadline day, with the north London outfit tracking Schalke's Julian Draxler throughout January
Goal exclusively revealed on Sunday that the club had dispatched a delegation to Germany to tie up a deal for Schalke star Julian Draxler and open negotiations with Frankfurt over a move for right-back Sebastian Jung.
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 them slip to third place in the Premier League should both Manchester City and Chelsea win on Wednesday.
However, Wenger was still satisfied with a point in a hard-fought game which, at one stage, they looked like they could lose.
"They have difficult games as well and we took at least a point," he added. "It's not enough but considering the situation at half-time, 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 suffered a fresh thigh injury that could keep him out for another six weeks.
