With the benefit of being the last teams to play in the group stage, both teams will have full knowledge of the knockout bracket by the time they kickoff at 6am - which may lead to the unusual situation of both teams attempting to lose the match.
Both Southgate and Belgium coach Roberto Martinez made wholesale changes, having already qualified for the next round, and neither seemed particularly concerned about winning. It felt like a proper World Cup match in the stands, even if it was a odd affair on it, with two of the best benches in World Cup history.
England then pushed on looking for an equaliser but they lacked a cutting edge.
It probably didn't sit well with Belgium's Michy Batshuayi either seen as we watched him celebrate his team's goal by kicking the ball causing it toricochet right back into his face.
England are now level on six points, goal difference and goals scored with Belgium, topping the group by virtue of their superior fair play record with one less booking.
Whoever finishes runners up of Group G will encounter Brazil or Mexico in the quarter finals, while the victor will face Sweden or Switzerland. With Belgium making nine changes and England eight.
Southgate gambled here. The outcome of this throw of the dice will be known on Tuesday.
England's support has swelled as the team have excelled in the tournament.
It was obvious Belgium's reserves of strength are vastly superior to England's - Martinez's dirt-trackers, to use a rugby phrase, are fitter for objective than Southgate's. The match came to be known as the Disgrace of Gijon.
Did England's undercard stake their claim?
Despite England pushing hard late on with a number of half chances they couldn't break down Belgium. Adnan Januzaj obviously impressed with his goal and Danny Rose caught the eye for England at left wing-back.
"Rashford should have scored and it's the one criticism people have of him - me included", he told RT. You want to have players available for the future, so you have to avoid yellow cards.
Reflecting on the defeat Southgate added: "It was a pretty even game".
England missed the likes of Jesse Lingard, Raheem Sterling and Dele Alli to fill that missing link in the team.
England now know what awaits them.
The team is to not look too far ahead in the tournament as this World Cup is very unpredictable, but instead focus on the fame against Japan. Any underestimation will be heavily punished. Winning Group G means a tougher road to the final. This has to be regarded as a plus. We don't like losing, we don't want to lose matches, but the primary objectives we wanted from the evening we've got. Moscow will be much more to England's liking.
Harry Kane's involvement is one of the tricky decisions facing Southgate.
