FIFA has changed the World Cup match ball towards the end of this year's tournament in preparation for the semi-finals and final.
The Al Rihla ball had been used for the group stage, last 16 and quarter-finals but has been replaced by the Al Hilm for the final four games of the competition, including the third-place play-off. Both balls are made by Adidas and have Arabic names, with Al Rihla translating to "The Journey" and Al Hilm translating as "The Dream".
The governing body announced the move on Sunday, ahead of the first round of semi-final games on Tuesday evening. Argentina will face Croatia at Lusail Stadium using the Al Hilm, before France face Morocco at Al Bayt Stadium on Wednesday.
