"He's played very well for Chelsea against some very good opponents".
Abraham, who has won two caps for the Three Lions before in friendlies against Brazil and Germany in 2017, had flirted with switching his global allegiance to Nigeria, who he qualifies for through his father. "But what a prospect".
Abraham, who has a Nigerian father, was born in London. He joined Chelsea as an under-eight player.
He did not remain hidden, for long.
For Tomori, it's a first ever senior call-up having previously been capped at Under 19, 20 and 21 level. The first game back after the worldwide break and then the League Cup tie.
Their situations are in stark contrast to just six months ago, when both players were out on loan in the Championship at Aston Villa and Derby County respectively.
Tomori is set to make his full worldwide debut after playing 15 times for the Under-21s, while Abraham could turn out for the senior England team for the first time since 2017. Owen Hargreaves famously did the same, choosing the Three Lions over Canada and Wales.
Callum Hudson-Odoi will also be hoping to break back into the England squad after he made his return from injury in September.
And with Mason Mount and Ross Barkley already in the squad from last month's wins over Bulgaria and Kosovo and Ruben Loftus-Cheek coming back to fitness, Southgate admits the two latest additions have earned their spot.
England could seal qualification for Euro 2020 with victory in Prague next Friday after picking up maximum points from their first four games.
