Ferguson has already signed Chris Smalling and Javier Hernandez for around £18million.
Reports have suggested Ferguson is ready to make a big-name signing this summer.
Gill said: “People say Alex is saying money is there because he has to. Anyone who knows Alex Ferguson knows he wouldn’t say that if he didn’t mean what he said.
“The money is definitely there. The financial results will show the figures are about £95m cash.
“We are not in a situation whereby Alex is restricted in what he wants to do with the club.
“We can invest in the players, the training ground and the stadium.”
