I'd rather Spurs in there. No Champions League sets United back, prevents them attracting and retaining top talent on and off the pitch, hopefully screws the Glazers on trying to pump the club's value prior to resale, and Spurs will always be shit, and the stadium debt will hold them back in or out of the four.
If Spurs scrape in this season, they're out the next. They have a pretty shit squad with most of its key players declining. Can't see a problem there.
Qwiss Spurs on the other hand will really struggle if they drop out now and probably get replaced long term by Newcastle in the top 6.
This future's coming anyway and we want that process dragged out.
