The stars appear to be aligning for both club and country.
The World Cup is a “motivating factor” for Hall, and there remain question marks surrounding just who will line up in his position for England this summer.
Hall, who has won two caps for his country, has yet to earn a call-up under Thomas Tuchel following an injury-disrupted period in his fledgling career.
But that will surely change when the England manager announces his squad for the friendlies against Uruguay and Japan on Thursday.
Tuchel certainly knows him well.
The England boss handed Hall his debut at Chelsea at the age of just 17 in 2022, and has watched the left-back play against his former club and Manchester City this month.
Hall was a highly-rated talent at Chelsea, but he has come a long way since Tuchel first trialled him in a back three against Chesterfield.
Arno Michels, Tuchel’s long-serving assistant at Chelsea, Bayern Munich and Paris St-Germain, knows that better than most.
“It’s incredible to see how Lewis has developed – and he’s still only 21,” he said.
Yet Hall will not be getting carried away.
Hall, by his nature, is a level-headed character, who does not tend to look beyond the next game, and has been kept grounded by a tight-knit family.
He has never lost touch with his roots.
The defender still has a small circle of close friends and has returned to Binfield, where it all started in Slough, in each of the past three summers to hand out trophies and medals at the annual junior football tournament he once played in.
Hall has even been back to represent his local cricket club as relatively recently as 2024.
The left-back has not forgotten those who have helped him along the way, either, such as Mark Robinson, his former manager with Chelsea’s under-23s.
Hall even jumped into the stands to catch up with Robinson after Newcastle’s 1-0 win at Stamford Bridge at the weekend.
“There’s lots more to come because Lewis is a very humble lad,” Robinson said.
“I can’t see that ever changing. You have got to keep learning, keep improving, and he will do that.”
