After finishing on the losing side in the Copa America final as Brazil hammered Argentina, Tevez is now preparing to fly into Manchester for a medical which, under normal circumstances, would mark the end game in a £30million move from West Ham.
However, with the Premier League insisting any deal must be done directly between United and the Hammers rather than Kia Joorabchian the saga is some way from conclusion.
Red Devils' legal expert Maurice Watkins has remained in England as efforts to resolve the dispute intensify.
And, after landing in Tokyo with the United party at the start of the club's four-match Far East tour, Gill confirmed United's intention to make Tevez their player.
"We are working on it," he said. "In my opinion, it has become over-complicated. Effectively, we are trying to work with four parties; the player, West Ham, the company who own Carlos' economic rights and the Premier League in order to sort it out.
"The process is ongoing. The player will have a medical at some point this week, then we will take it from there.
"We still have to sort out the paperwork but we are confident that can be achieved in the course of the next week or so."
