Saudia Arabia will go up against Egypt on Monday, June 25 at Volgograd Arena. The stadium was built on the site of the demolished Central Stadium and its roof rests on a cable frame arranged to form a bicycle wheel pattern created by steel-wire cables. 

The match will kick-off at 3pm BST (10am ET, 7am PT, 12am AEST) - so that's 5pm for locals wanting to see how Group A plays out. Fans in Saudi Arabia can watch the game at 5pm and fans in Egypt can tune in at 4pm.
