I could tell you! It wasn't all that much actually because it was Leicester in fact it was longer odds for them to retain it than go down: 33/1 vs 25/1
Imagine those Leicester relegation odds though, if they were accumulated with separate bets for not losing in all 6 of the CL group stage games > going through the Round of 16 head-to-head > ditto Quarter finals > ditto Semi-finals and then winning it
Doing it this way could achieve approximately 300x more than I was offered when I first asked, in June last year, for the straight odds for "this year's PL champions to be defending the 2018 CL title from the Championship"
Never gonna happen , but what's £2 between friends?
