Belgium defeated Algeria 2-1 in Group H's opening match, but it was a tough game for the European side and they had to come from behind to take the three points.
Jan Vertonghen's foul gave Sofiane Feghouli the chance to open the scoring and the African side led at the break as a result.
Marc Wilmots, the Belgian coach, responded with three substitutions within 20 minutes of half-time—and two of his subs did the damage. Marouane Fellaini headed the equaliser, before Dries Mertens ran into space to slam in the winning goal.
Korea Republic and Russia are the other two teams in the group which looks extremely tight, even if Belgium have eventually taken the win which was expected of them.
