But if Sale take over they can impose their own terms and conditions on us, benefiting at our expense

Because it would give them primary tenancy in a fantastic stadium (along with any future revenue streams it and the surrounding developments may generate)
Because they could take the best bits of the competition for their own benefit (i.e things like our youth development, the schools work/community stuff we do etc)
Because Wilky said he'd sell up to the right person (who may say one thing now and do something completely different shortly after, like Kraft did with Cadbury)

I don't mind Sale sharing the stadium if it means a reduced cost to Salford which we can spend elsewhere. My fear, as i've written elsewhere on this forum, is what will become of us if further down the line Sale take us over

I'm sure some sort of covenant would be drawn up if that was to happen, i really wouldn't worry.

I think the problem with Sale moving in is that it'd become harder to attract new support. Sale aren't a bad side, and if they push on to become a 'North West super club' then I reckon people would rather go and watch them instead of Salford in the bottom 4 of Super League (hopefully not of course, but given what I've seen so far, I can't see any other outcome this season). Plus, don't we need an average of 8000 to break even, or something along those lines?

The football club started hitting trouble after Sale had moved in. They've also been left to rot since, despite all kinds of promises that the deal would benefit both clubs.

Hopefully the fact that it's the stadium company that own the place will stop anything from happening. But if they ever get into trouble... No, not worth thinking about.
