Old Firm will be seeded
As Scottish champions, Rangers go straight into the third round draw, on July 29.
If runners-up Celtic overcome their second round opponents, both Old Firm rivals would be seeded in the third round draw, meaning they would avoid being paired with the likes of Manchester United, Inter Milan, Ajax and Monaco. Panathinaikos, Sporting Lisbon, Werder Bremen, Villarreal, Rosenborg, Slavia Prague and Club Brugge are also confirmed seeds.
