i think the question is ok, but each person will have a different definition of what counts as "sufficient money".
I'm convinced we have a lot more money than has been spent so far, but will that be enough.
Have we got enough to buy 11 players of the standard of the top 3. (not all in one summer). That would cost us around £200mill as a minimum, which you could say would need £50 million each year over the next 4 years.
i believe Randy would be willing to spend that, as we would end up getting about £25mill back each year in extra revenue from Champ League, merchandising, extra gates, more matches, etc...
