The Brazilian-born Croatia international was embroiled in controversy after the qualifier against Celtic when he was adjudged to have dived and handed a two-match ban.
But Fifa overturned the ban and Eduardo was free to play in Belgium â€“ and duly netted the winner â€“ after Arsenal came back from 2-0 down to win 3-2.
Eduardo was also caught out as Standard scored in the opening minutes, failing to clear a corner, and Wenger knew that he would have the final say.
â€œIt is always inevitable with Eduardo," said the Arsenal manager.
"He was caught out on the first goal but he is a guy who can always turn up on crosses because he has that anticipation."
