#5 Mason Mount
Having been at the club since the age of 6, Mason Mount is a Chelsea player through and through. Always humble and grounded, Mason Mount has made his way through the ranks as an attacking midfielder with his grit and determination to play for the first team one day.
And from the looks of it, he is well on his way to becoming a first team player soon. He is as much a fighter as a smooth operator (Imagine a blend of Michael Essien and Michael Ballack). Mason Mount is an example of how players must compose themselves even at youth levels. Though he might not realistically get a chance at Chelsea, he will be an invaluable asset to any team in the near future.
We can see that Chelsea has been doing an exceptional job at youth Development in the last decade. But the reality remains that Loftus-Cheek has been the only player to get meaningful first team minutes since Josh McEachran. The problem has clearly been at Youth integration rather than the development. But with Antonio Conte now at the helm, the future looks better for the academy graduates.
Roman Abramovich genuinely wants to bring up exciting homegrown talent into the first team given the amount of time he spends watching the youth teams and the staff he has recruited to give it his best shot. There will definitely be a day when having three academy graduates as substitutes will be a norm and not an exception.
