Wenger was barracked by his own support towards the end of his time with the Gunners.
But he told BBC Sport: "I don't believe you should rate highly what a fan says in the moment - a fan says something based on the moment, based on emotions. Today it seems the minority has a big dictatorship. They dictate what is talked about, therefore if you have 50 people on social media being negative it can somehow get more attention than 60,000 people in a stadium.
"It doesn't mean everybody has to do what they talk about. If you look at our last three years you will see in 2016 we finished second - OK, it was behind Leicester City but every other club finished behind Leicester too and they lost only three games. In 2017 that was the first time we were not in the Champions League since 1997.
"So, yes, I wish we had maintained that record but I think this year we have a good chance in order to be back in the top four."
