Can’t rule anything out in football. Chelsea finished 10th in 2015/16 on just 50 points, only 13 points above relegation. They won the league the next season with 93 points, a 43 point swing. When it clicks and you get a good start, anything can happen.
Yeah, or maybe they finished 10th because Mourinho had a fucking meltdown.
They won the league with 87 points in 14/15, the same players won in 16/17.
Completely incomparable to Arsenal or Spurs picking up 25 points out of nowhere when none of them have won anything.
