Hard to understand the way Arteta is thinking about his club. I also wonder how he's so obsessed with his rival's players. He brought Havertz, Jorginho, then Sterling (worst ever), Kepa and now Madueke. It gets worsen with how he paid Madueke for 50m, while Chelsea bought him for 29m.
In the latest update, Arsenal is in the progress signing Gyokeres from Sporting. I guess if that transfer doesn't work out for Arteta, and he can consider to sign Jackson from Chelsea.
Arsenal last signed really interested for signing Chelsea's player from Havertz, Jorginho, Sterling, Kepa and right now signing Noni Madueke, still waiting the amazing signing by Arsenal in this transfer moment will get success for signing Gyokeres although the players have announced leave his club but Arsenal not negotiation yet. I don't see any good progress did by Arsenal for signing Gyokeres without have officially bid offer for Sporting Lisbon and likely they want fees transfer around 80 to 100 million euro.
