This is a difficult message to write to the @Arsenal fans that I’ve played for over the past few years. I’m really deeply disappointed by the fact that I have not been registered for the @premierleague season for the time being. Upon signing my new contract in 2018, I pledged my loyalty and allegiance to the club that I love, Arsenal, and it saddens me that this has not been reciprocated. As I have just found out, loyalty is hard to come by nowadays. I've always tried to remain positive from week to week that there's maybe a chance to get back in the squad soon again. That's why I kept silent so far. Before the Coronavirus break I was really happy with the development under our new coach Mikel Arteta – we've been on a positive way and I would say my performances were on a really good level. But then things changed, again, and I was not longer allowed to play football for Arsenal. What else can I say? London still feels like home, I still have many good friends in this team, and I still feel a strong connection with the fans of this club. No matter what, I will keep fighting for my chance and not let my 8th season at Arsenal end like this. 🙏🏼🙏🏼 I can promise you that this hard decision won't change anything in my mindset – I will continue to train as best as I can and wherever possible use my voice against inhumanity and for justice. #M1Ö #YaGunnersYa
