Born in Calgary, Tomori moved to London as a one-year-old but opted to represent his country of birth at schoolboy level with England having not initially called him.
His Canada call threw him together with Davies, who was the youngest player in the squad at the time, and Tomori opened up about fate once again bringing him together with the highly-rated Bayern youngster.
"I remember when the squad got announced the media was talking about the 15-year-old that was playing for Canada Under-20s. It was Alphonso Davies," Tomori told Goal as he was unveiled as an EA SPORTS FIFA 20 Future Star.
"I actually hadn’t heard of him before and we got to the camp and we were sharing a room. I was like ‘oh, I am sharing a room with a 15-year-old’ and I was 18 at this point. But we actually got on really well.
"That was maybe three, four years ago, but since then we have kept in touch and we have got each other on social media. I have actually just spoken to him literally just before I got here today.
"Obviously, he plays for Bayern Munich and we have got each other in the Champions League. We have been talking about the game and we catch up every now and again. Back then, you could see there was something.
"Being at Bayern Munich has obviously improved him massively but back then if you didn’t know you wouldn’t say he was 15 from the way he was built and playing.
"It is obviously a big challenge [to face Bayern]. We know how many quality players they have and what they can do. But these are the kinds of games that suit us as a team. We like the big stage and we like to win big games and play in the big games. We want to progress."
Tomori had a tough time at Cobham watching the likes of Tammy Abraham, Dominic Solanke and Mason Mount earn calls to the England youth set-up while he waited at home over international breaks.
Now a full England international, it is easy to forget that the 22-year-old was overlooked for a long time.
It was a match against the Three Lions in 2016 - and Manchester United's Marcus Rashford - that arguably put him on the map.
Tomori was playing centre-back for Canada against Rashford, who had just scored the winner in the Manchester derby, after goals on his league and European debuts against Arsenal and Midtjylland respectively. Tomori helped Canada produce a shock 2-0 win.
“I remember Rashford just burst onto the scene and he was scoring loads of goals for Man Utd," he said. "He was the talk of English football. Going into that game, I was really focused on doing as well as possible.”
Tomori has produced in his maiden Champions League season too, with good displays against Ajax, Valencia and Lille in the group stage behind him. The youngster has been with Chelsea since he was eight years old, and was 14 when he watched his club win the competition against Bayern in 2012.
"I was at Chelsea at the time and wanted Chelsea to win. When they won it, I remember my friend called me immediately and he was just screaming down the phone.
"I remember when me and my dad first went to a Chelsea game. We were sat literally next to the tunnel and me and my dad were looking at each other and we were like ‘they don’t look real, they don’t look like real people, they look like robots’.
“Back then it was surreal but now you see these people on a regular basis so you just realise they are regular people and it has kind of sunk in now."
