Absolute rubbish.
Bristol finished third in the then GP after promotion, more than Sale have achieved in that period. Bristol have twice finished top of the Championship , and twice failed in the playoffs including the season LW were promoted after they finished fourth. LW weren't the best team that year, just the most successful in the playoffs. Now Bristol have finished top for the third time, been the most consistent side again (thus most suited for the AP) and set records for attendance in the championship league structure. Bristol have been building for years, just like many of the other Championship clubs
For a Sale fan to begrudge Bristol success because they have a backer is most hypocritical. It's not as if Sale is a profitable business and doesn't need external investment to operate, or "buy success" as you put it splashing the cash around like there's no tomorrow signing the likes of Cipriani. Last season you were in the relegation battle so a little humility wouldn't go amiss. By your standard surely you bought success this season by signing better players than the last to avoid said battle again. Also of interest to you, when LW were promoted they actually had a larger playing budget than Bristol as reported around the time yet average attendances of 4000 lower than them. How do you think a club like LW operates if not also from wealthy backers?
Take them chips off your shoulders.
