Rooney signed a new five year deal with the Red Devils on Friday night work a record £300k a week.
The England man went on to put in a sterling display against Crystal Palace last night, bagging a fine volley to put the game beyond doubt in the process.
Neville believes that if United didn’t pay Rooney that amount then another club would and with the difficulty they would have to replace him evident, the former United full back agrees that it was a vital piece of business by David Moyes.
“[Getting him to sign a new deal] was critical for them because replacing someone of Wayne Rooney’s goalscoring record is near-on impossible,” Neville said.
“If you are going to do it you’re going to have to spend £50-£60million or get very lucky and unearth someone yourself.”
