While the likes of Lionel Messi, Lautaro Martinez and Angel Di Maria adorn the Argentine roster, Saudi Arabia contain far fewer household names as they aim to cause an upset.
The Saudis are major underdogs to make it out of a group which also contains Mexico and Poland, so anything they could get against one of the tournament favourites would be considered a bonus.
