Ferguson went on a major spending spree 12 months ago, bringing in Owen Hargreaves, Anderson and Nani within weeks of the Premier League being won and adding Carlos Tevez after a protracted battle over his registration.
And Gill has already promised Ferguson cash will be available this summer should the Scot push through plans to make his group of players even more formidable next term as he looks to equal Liverpool's record haul of 18 league titles.
"Like any club you assess what's gone well, what hasn't gone so well and where you feel you can improve," Gill told MUTV.
"We will certainly be in a position where, if we can improve it, we will.
"Alex will never allow us to rest on our laurels. It is the best league in the world without doubt so if we want to continue to be at the top we have to make sure we look at the squad and improve it.
"The team won the title last year so how do you improve on that?" said Gill.
"But that is what we try to do. We need to make sure we don't stand still and our ability to identify those players who will make that difference has been very well sorted out the last two or three years."
