Pull A Belgium

To seem as if one has completely lost a battle at first, but eventually defeats the opponent with an unexpected comeback, luring the opponent into false hope.

Refers to the Belgium vs Japan World Cup 2018 round of 16 match where Belgium won 3-2, yet Japan was once up 2-0 before conceding three straight goals to close the game. Japan thought they had it.
