Been trying to avoid this thread as I knew I'd get drawn in and far too involved, but I've decided to yield and throw in my take.
Yes, I would like to see us hold on to sixth and qualify for the Europa, and these reasons are why:
1 - I'm not sure we'll have another chance to finish above Manchester United for the first time since the inception of the Premier League in the near future or ever in my lifetime again (and I'm young). It may sound trivial, but it certainly matters to me. After growing up with a lifetime being surrounded by bandwagoning Man U fans, it has been succulently enjoyable to see them ache with pain for the first time or even abandon the team altogether. I do not want the ones that have remained loyal, and that have compared and contrasted our brutal seasons with me, to suddenly have the ammunition to flip it on me and other Spurs fans by saying that after everything they went through they still managed to finish above us. Because they inevitably will. Call it naive, juvenile, etc I don't give a fuck, I very much want to see us finish above Manchester United.
2 - I think next season needs to be viewed as a rebuilding season anyway. Given the state of our unbalanced current squad, which is also leaderless and gutless; and the timing of the World Cup, having to bring in yet another new manager, and that some of the other teams around us will likely be strengthening significantly this summer, I think it would be unreasonable for us to expect top four next season anyway. What is reasonable however, is to expect to see a plan in place, progress in efficiency of play (possession and effective chances created in attack in particular), and to not be thumped again next year by anyone. While the Europa would likely limit our prospects on following weekend matches, it would afford a redeveloping squad more time for interaction and the manager more time for assessment.
3 - Put simply, I enjoy watching us play in Europe. If the aforementioned were all negated for a variety of reasons and we were under different circumstances, those things very well likely would overcome my wish to see us play in the tournament that has undoubtedly cost us vital points in recent seasons. But as things stand, I think it would be to our benefit.
