Why do Chelsea fans banter Arsenal so much

They don’t mind Manchester City or Liverpool winning the league as long as it’s not Arsenal.
Chelsea have really improved this season. I didn’t think Enzo Maresca was going to be a good match for Chelsea but he is constantly proving me wrong. Chelsea have maintained a good run this season despite the internal crisis that is happening with the club ownership.
I think the case between Chelsea fans and that of Arsenal is similar to what we see happening between Manchester United fans and the Liverpool fans they are always wishing each other bad eve when the team is playing against none English teams they want the other teams to defeat the English Premier League team that are playing I think it's all about choice of team and selfish interest nothing much if you asked me.
No doubt there is a great change and a higher rate of improvement in the Chelsea team all thanks to Enzo Maresca who brought about the change with the numbers of players he brought in for the club and the amount of money he spen far, he has turned the poor performance of the team around and the team is doing very well now and their results in the last few games shows that he knows what he's doing as the manager.
I think the hatred comes from the fact that Arsenal fanbase can be so intolerable. Among the top clubs in the Premier League history, Arsenal has the least number of silverware. The last time Arsenal won the EPL was in 2003-2004. They dubbed the year as the year of the ‘invincibles’ year. Funny enough Arsenal have never won the Champions League but their fans are the loudest. Imagine what would happen if they win the EPL, we would not hear the last of it. I think that’s why everyone is happy that they keep bottling the league.
