The Gunners, who head to Brighton for Saturday's FA Cup fourth-round tie, have been linked with a string of players across Europe, including Barcelona's David Villa and Borussia Dortmund defender Mats Hummels, and West Ham's combative midfielder Mohamed Diame.
However, the Arsenal boss insists his main focus ahead of the close of the January transfer window is on maintaining performance levels on the back of their midweek 5-1 thrashing of West Ham at Emirates Stadium, which kickstarted their Barclays Premier League campaign.
The Frenchman said: ""What I worry about is getting the players who have been injured back fit, to get the players who play for this club to perform at full potential.
"If we perform at full potential we cannot expect any miracle from outside, we want to make things happen inside.
"If someone else can strengthen our squad, we will do it of course, but we have the resources inside to do well.
"We have two players in every position, that should be enough, plus the young players in behind.
"But if we find the top-class players in any position, we never refuse to strengthen our squad."
Wenger also went to deny speculation that he had lodged any formal bids for the trio of stars which have been mentioned, while stating his disproval of the whole January window system.
