England were 86 seconds away from an embarrassing Euro 2024 exit until Jude Bellingham's stunner inspired a 2-1 extra-time win over Slovakia in the last 16.
The Real Madrid midfielder had been visibly frustrated throughout the game in Gelsenkirchen as he and his team-mates laboured to what appeared yet another dismal exit on the international stage.
But Bellingham - who only turned 21 on Saturday - showed his talismanic quality yet again to haul England level with their first shot on target in the 95th minute. His superb bicycle kick from a long throw-in beat Martin Dubravka to cancel out Ivan Schranz's first-half opener and send the tie to extra-time.
Harry Kane then stepped up 50 seconds into the additional 30 minutes to nod home Ivan Toney's flick and give England a victory which sets up a quarter-final with Switzerland next Saturday (kick-off 5pm), which had looked almost impossible only moments earlier.
The recriminations were already beginning on what looked set to become another of England's darkest nights where they were outplayed for long periods by the team ranked 45th in the world. Despite that, Southgate appeared reluctant to influence change on the pitch, with his only substitution before the 82nd minute the introduction of Cole Palmer after Kieran Trippier was forced off with injury.
Long before that, Schranz had fired Slovakia into a first-half lead with his third goal of the tournament. The Slavia Prague winger was allowed to stride forward from midfield past Marc Guehi to meet David Strelec's ball into the box before beating Jordan Pickford one-on-one.
England continued sleepwalking towards the exit door when Bellingham's poor pass on the half-way line was intercepted by Strelec, and Pickford could only watch on in anguish as an ambitious effort drifted past his unguarded far post.
