Chelsea's spending power has dominated the past few transfer windows, but it was the departure of their latest academy graduate Armando Broja - initially on loan to Fulham - which was arguably the most interesting deal of a quiet deadline day.
The Blues are open to selling both Broja and fellow youth product Conor Gallagher at the right price - highlighting an increasing trend of Premier League clubs offloading former academy players.
When clubs sell academy graduates, such as Manchester City's £40m sale of Cole Palmer to Chelsea in the summer, that entire amount goes down as 'pure profit' in their accounts and can help them navigate the top flight's strict profit and sustainability rules.
