The support has carried beyond the official fan-zone infrastructure. Groups reportedly gathered around Boston Common, with songs, flags and celebrations continuing into the evening.
The mood is fuelled by Morocco’s progress through the tournament:
That route has created confidence without removing the pressure. Morocco’s supporters are not travelling merely to celebrate another deep run. They want a result against the team that ended their historic campaign four years ago.
France’s semi-final victory over Morocco in Qatar remains the emotional centre of this fixture. The previous meeting established Morocco as a serious tournament force, but it also left a sense of unfinished business among supporters.
The players and coaching staff may avoid revenge language, yet the crowd has embraced it. That contrast could define the occasion: Morocco must use the atmosphere as energy rather than allowing the history to become a distraction.
Morocco could be without Ismael Saibari, with the report saying the midfielder suffered a thigh injury in the previous match. Any absence would reduce selection options at the point when tactical discipline matters most.
France, meanwhile, possess the clearest individual threat in Kylian Mbappe. His pace and finishing demand a near-perfect defensive display, particularly if Morocco are forced to chase the game.
The next storyline is whether Boston’s red tide can translate into control on the pitch. Morocco have the emotional advantage in the stands; France have the experience and Mbappe. The quarter-final will decide which force carries greater weight.
