United finally completed the signing of Carlos Tevez on a two-year loan last week, after the deal was ratified by the Premier League.
The transfer of Tevez was complicated by a dispute over his ownership and the complex nature of his contract.
Gill commented: "I wouldn't disagree that the third-party ownership needs clarifying. It needs Fifa to do something.
"As a club, you need to step back, look at it and understand it.
"Ultimately, we want to secure the services of a player, under terms we believe are appropriate and acceptable for a period that we want, and, in the nicest possible sense, we control the player, in the nicest possible sense, during that period."
United have the option to turn Tevez's transfer into a permanent move at any stage over the next two years, and Gill is happy with how the matter was concluded.
"Everything is in place for Carlos and Manchester United to agree a long-term deal and we are very comfortable with the arrangement," said Gill.
"We are looking at it very positively with a view that he will be the player he can be for Manchester United and that it will be an easy decision to exercise our option.
"That is our goal. We are not looking at two years, we are looking at a long-term arrangement."
