Tottenham staying up last year was pure luck.

Was Villa in the Europa League semifinals?
Ahead of their match against Nottingham, they rotated their full squad at home against Tottenham, and Tottenham won 2:1.
If Villa had fielded their full starting lineup, they wouldn't have even managed 1 point, let alone 3.
Villa's home buff allows them to take down Man City, Arsenal, and Liverpool alike.
Since they ended up only 2 points ahead of West Ham, we really have to be thankful for that schedule.
If they had met one match earlier, it would have been certain relegation.
