Before the summer of 2019, if you had told anyone inside or out of Chelsea that in under two years, an academy graduate would have a defining say in a Champions League final, you might have received some chuckles.
Any further back, and it would have seemed fanciful. Although a section of supporters are concerned that the club may be open to passing up on some existing academy talent, it is beneficial to gauge how much progress has been made in a short space of time.
The pretty transformative summer of 2019 when Frank Lampard replaced Maurizio Sarri will mostly be defined by its influence in opening the door for the likes of Mason Mount.
