Of course! When a club comes into money, it can be a great opportunity to invest (stadiums, training grounds etc.) and buy players that improve the squad. It's also an opportunity to squander it all :D I'd laugh if they did the latter.
That's an irrelevant argument. They DO have the prem money so they can "live" within that budget like all the other Premier League teams.
We'd be doing the same if we were in the PL as we'd have this large income source that we currently do not.
