Despite the slender win, Wenger admits that he was not happy with the lack of openings created by his side.
"It was disappointing we didn't create more chances tonight than we did but that is because Anderlecht defended very well," the Frenchman is quoted as saying by FIFA.com.
"But the turning point was not to concede a second goal - they had a big chance that they didn't take and our experience made the difference. It is a bit unexpected to take the three [points] considering the quality of match that Anderlecht played tonight."
