Tottenham must hope Real Madrid beat Liverpool in the Champions League final, otherwise Spurs face being in the third pot of seeds for next season's group-stage draw.
Spurs were handed an incredibly tough draw from Pot 3 this season but still emerged as group winners ahead of Real Madrid, Borussia Dortmund and Apoel Nicosia.
After reaching the knockout rounds they would have been hoping that an improved European coefficient would move them up to Pot 2, therefore increasing the likelihood of a more favourable draw.
But Sporting's failure to beat Maritimo on the final day of the season in Portugal on Sunday cost the Lisbon club a place in the Champions League, gifting a berth instead to Benfica, who are ranked higher in UEFA's coefficient table than Spurs.
If Real Madrid win the Champions League, then they will take the place for the holders in Pot 1, meaning Tottenham move up from Pot 3 into the vacant position in Pot 2. Liverpool would thenbe in Pot 3.
However, if Liverpool win the Champions League then they will leapfrog from Pot 3 to Pot 1 as holders and leave Spurs in Pot 3.
Provisional draw pots (*denotes qualification to be confirmed)
Pot 1: Real Madrid or Liverpool, Barcelona, Bayern Munich, Manchester City, Juventus, Paris Saint-Germain, Lokomotiv Moscow, FC Porto
Pot 2: Real Madrid or Tottenham Hotspur, Atletico Madrid, Borussia Dortmund, Manchester United, Shakhtar Donetsk, Benfica, Napoli, FC Basel
Pot 3: Tottenham Hotspur or Liverpool, Roma, Dynamo Kiev, Schalke, Lyon*, Besiktas*, Monaco*, FC Salzburg
Tottenham's only other hope to find a way into Pot 3 is that either Benfica (third qualifying round) or FC Basel (second qualifying round) fail to make it to the group stage, and both will be seeded through qualifying.
