Bale cracked in a superb last-minute strike to secure a 3-2 win at West Ham on Monday night, which moved Spurs up into third place in the Barclays Premier League.
The Welshman - once scouted by Arsenal when a youngster at Southampton - is being heralded as one of the best in Europe, up alongside Cristiano Ronaldo and Lionel Messi.
Wenger, though, insists his team must concentrate on delivering a performance themselves rather than worry about what Bale might do.
"We don't plan for anybody. It is always the same - focus on our strengths and forget about your opponent," said Wenger.
"There is nobody special that you least like to face. All players have different qualities.
"What is important when you are a manager is that you are focused, that hasn't changed over the last 15 years, you always make sure your team is at its best, prepares well and focuses on playing the football that we love.
"What is important before a game like that is just to focus on our game and forget all the rest."
