To this point, Gareth Southgate has preferred a double pivot of both Dier and Henderson, but recent England games have shown just how much Harry Kane and Dele Alli miss a creative midfielder (for England this would be Adam Lallana) and the need to play both Marcus Rashford and Raheem Sterling.
It's clear that if England want to start thrilling fans and beating quality sides, they need to switch to 4-3-3.
That means just one defensive midfielder, so does who plays?
Since Dier entered the league in 2014, he has played 112 games in the Premier League. Jordan Henderson has managed 87 games in that same period. Dier has played 9487 minutes whilst Henderson, a more injury-prone player, is over 2000 minutes shy of that on 7476.
Dier has attempted an impressive 53.26 passes per game, completing 44.76 for a completion of 84%. He's attempted 6.53 long balls, completing 3.87 at a 59% ratio.
When it comes to through-balls the Spurs man is found wanting, he's made just 0.05, completing 0.02.
It's clear that he's a decent passer, but functional at best.
Henderson meanwhile has attempted 67.84 passes per game, 56.20 of which found their target. That's 83% completion.
When it comes to long-balls Henderson has sent an incredible 8.28 balls hurtling into an opponent's half, with 4.62 finding their target. He's a long-range master. In terms of through-balls he's attempted 0.32 and completed 0.13. Henderson has created 1.51 chances per game, way ahead of Dier's 0.45.
Dier has attempted 1.71 tackles per game, winning 1.32 (77%). He's made 1.57 interceptions. 0.48 blocks and an incredible 3.20 clearances.
Henderson meanwhile has attempted 2.72 tackles per game, literally more than one more a game than Dier; yet he's only won 1.91 for a completion of 70%. He's made 1.18 interceptions. 0.15 blocks and 1.48 clearances.
Whilst Henderson is a better passer, Dier is unquestionably a better defender. He attempts less tackles but when he does he's more sturdy in the challenge, moreover his other defensive numbers are way up. In a 4-3-3 behind Dele and Lallana, this defensive power would be invaluable.
Moreover Dier's ability to play in a back three would also mean that England could seamlessly switch from a 4-3-3 to a 3-4-2-1 without making a single substitution.
That kind of tactical flexibility and defensive strength, coupled with his increased physical reliability (Henderson is never far from his next injury) mean that, whilst Dier probably won't retain the captain's armband when competitive fixtures roll around, he should definitely be England's defensive midfielder of choice.
