Arsenal have a knack of signing players who should easily embed into the squad.
Jorginho and Kai Havertz were already friends when Havertz arrived at the club, while Oleksandr Zinchenko and Gabriel Jesus knew each other and Mikel Arteta well from their time at Manchester City.
Raheem Sterling joined Arsenal with an almost perfect set of circumstances.
Sterling already knew Zinchenko, Jesus and Arteta from his time at Manchester City, while he worked with Kai Havertz and Jorginho at Chelsea, as well as several players from England duty.
