They are a shitty club right now, they are not even doing it good, and they are just promoting cryptos in order to be more "famous" haha, what a nice marketing campaign in there.. I can really smell that.
I think that their ICO could be a huge success and purely because of this news, I've seen it well publicised across English news and it's a big step. Let's not forget that ultimately Arsenal FC are a business and they have not enjoyed the success they've had over the years without being able to make business decisions, they would not partner with this crypto if they foresaw that it was going to fail.
