The centre-half, who has played every minute of the tournament for the Red Devils to date, as has Jan Vertonghen at left-back, powered home a header from Kevin De Bruyne’s wide free-kick in the 10th minute in Toulouse.
It was his second international goal, the first having come against Japan in a friendly in November, 2013, and saw him join England’s Eric Dier – on target in the Three Lions’ opening game against Russia – on the roll call of Spurs players to hit the back of the net in France this summer.
Both Belgium and Hungary had chances to add to the scoreline in a really open game before three goals in the last 12 minutes from Michy Batshuayi, Eden Hazard and Yannick Carrasco put the Red Devils out of sight.
While Toby and Jan came through the full match, Mousa Dembele watched on from the substitutes’ bench. He picked up a knock earlier in the tournament.
Belgium will now meet Ben Davies and Wales, who famously beat them in qualifying, in the quarter-finals on Friday.
