80 pts being a legitimate challenge means Le Arse will have to be in relegation form for 15+ games out of remaining 22. You see that happening?
Meanwhile, if they were to get to 90 pts, that means 47 out of 66 = a leeway of 5 losses and 2 draws, top 4 pace rather than title winning form, while if we are to get to 90 pts, we need to get 58 from 66, can only lose twice and draw once. Then there’s also the small matter of GD.
It’s nice and all to dream, but cold hard numbers just don’t support that hypothesis, looking at the respective form of the 2 clubs.
