Victory would have seen Arsenal join Borussia Dortmund in the next round of the competition but poor defending allowed Anderlecht the chance to secure a famous draw in London.
After the game, Wenger said:
"We had a poor defensive performance from the first until the last minute. We never looked comfortable and we got punished. Annoyed? Yes. It is very disappointing. We were very poor."
He also admitted that perhaps his players underestimated Anderlecht, despite being pushed all the way at the Constant Vanden Stock on matchday three.
"In the Champions League you need to be at your best mentally and we weren't today. Maybe subconsciously we underestimated Anderlecht at 3-0."
This morning transfer rumours are circulating, including one that sees Arsenal muscling in on an apparent Tottenham target. Instead of bringing in German holding midfielder Sami Khedira they are instead believed to be keeping tabs on Christoph Kramer.
The talent, who started the summer's World Cup final against Argentina, has been out on loan at Borussia Monchengladbach from Bayer Leverkusen for four seasons now. He is rumoured to be available for £12 million.
He also recently made these comments, suggesting he was open to a potential move:
“In general, being involved in the football business is often like modern human trafficking.
“But for me, a contract can say whatever it wants. If I don’t want to play somewhere next season, I won’t play there. In the end, I will still decide where I play.”
