It's official, Karl Hein has finally earned his promotion to the Arsenal first-team squad.
In truth, this plan of action has been in the works for well over a year now as after the 20-year-old committed his future to the club last summer by signing a new long-term contract he was involved in the 2021/22 senior squad photocall alongside Bernd Leno, Aaron Ramsdale and Arthur Okonkwo,
However, there was no forthcoming announcement regarding a permanent call-up to the first-team squad and Hein was loaned out to Reading during the second half of last season - although that spell was cut short due to an unfortunate injury and the Arsenal youngster has spent the summer returning to full fitness.
