Chief executive Ivan Gazidis may have talked up the Emirates Stadium club's new "financial firepower" at the end of last season, but so far the only confirmed signing has been France Under-21 forward Yaya Sanogo, and that on a free transfer from Auxerre.
Arsenal, who failed to land Real Madrid's Gonzalo Higuain earlier in the summer, continue to pursue wantaway Liverpool striker Luis Suarez, but will have to up their bid to closer to £50million with the Reds unwilling to sell.
Bayern Munich's Brazil midfielder Luiz Gustavo is a target, while 20-year-old Lille winger Florian Thauvin is another said to be on Wenger's radar, as is Romania forward Ciprian Marica following his release by Schalke.
While the Gunners boss clearly is determined to bolster his squad, albeit not in time for next week's crucial Champions League play-off first leg against Fenerbache in Turkey, Wenger accepts patience will be key as the clock ticks down towards the September 2 deadline.
"We are active," Wenger told Arsenal Player. "We are in a situation like Manchester United, like Chelsea, where everybody expects signings and at the moment not a lot has happened.
"There are 18 days to go, so that is a long time in the transfer market and we will be active.
"I cannot certify what the number [of players coming in will be], but we will be active until the end, that is for sure."
Although Wenger may have so far been frustrated in his plans to strengthen the team, at least several fringe players have been taken off the wage bill, with the exits of Gervinho and Marouane Chamakh both now confirmed.
Wenger feels Ivory Coast forward Gervinho, who signed for Roma in an £8million deal, had been unable to overcome the negativity from some Arsenal supporters.
