Last season Hull played Trencin in the 3rd qualifying round (won 2-1 on aggregate) and Lokeren in the play-off round (lost on away goals 2-2 on aggregate). Spurs meanwhile played AEL Limassol in the play-off round (won 5-1 on aggregate) and were in the post of first seeds in the group stage. Everton went straight into the group stage, and were in the pot of third seeds.
The season before that, Swansea played Malmo in the 3rd qualifying round (won 3-0 on aggregate) and Petrolul Ploiesti in the play-off round (won 6-3 on aggregate). They were in the post of second seeds in the group stage. Spurs meanwhile played Dinamo Tbilisi in the play-off round (won 8-0 on aggregate) and were in the post of first seeds in the group stage. Wigan went straight into the group stage, and were in pot of second seeds.
So if next season roughly follows this pattern, we should hopefully not face too much issue with these two qualifying rounds (in terms of standard of opposition - I think Hull and Swansea were both seeded, so I see no reason why we would not be too on that basis), and will then find ourselves either in pot two or pot three come the group stage should we get there.
