Yes. You've provided one terrible 'source' - the Mail, and one musing from a half reputable source. Notice he doesn't state anything of the sort, just wonders if it is true or not.
They also know that, with rival clubs now structuring contracts with lower basic salaries and higher incentives, they would be within their rights to do the same with Rooney, but would he accept a pay-cut to stay?
He never says that United have asked Rooney to take a pay cut, just that other clubs are structuring their wages like that, and United are within their rights to negotiate Rooney's contract similarly.
