Was listening to Arseblog. James mentioned youth players might only be able to sign short contracts re Saka.
Looked this up. Basically, 17 year olds can sign a 3 year contract and 18 year olds can sign a year deal. Saka is 3 months short of 19. So he started heating up a tear after they’d done his deal. So not a massive surprise they were caught by surprise here. But a warning that they need to act quick in future.
