Andy Murray and coach Amelie Mauresmo are very close to formalising a deal that will see the pair work together for 25 weeks a year.
That was the intention when they agreed to a trial period over the grass-court season, which ended with Murray losing to Grigor Dimitrov in the Wimbledon quarter-finals.
A day later they met in London and resolved to continue the partnership - but as yet no contract has been signed.
However, that will happen very shortly, committing former Wimbledon champion Mauresmo to accompanying Murray to most tournaments.
The Scot said: "We're working together for 25 weeks a year."
Murray's decision to hire a female coach continues to attract attention, and his first-round opponent admits it is not something he would consider.
Murray opens his campaign on Monday against Dutch would number 70 Robin Haase, a player who has caused him trouble at Flushing Meadows before.
Haase said of Mauresmo: "I think in the end that you need to understand how the game works and I think that women's tennis and men's tennis is such a different game that it's tough to understand. Maybe I'm wrong. But that's just the feeling I have."
Murray hired Mauresmo two-and-a-half months after splitting from Ivan Lendl, who was no longer prepared to commit the amount of time to their highly-successful partnership that Murray wanted.
They remain on good terms and enjoyed a brief reunion at Flushing Meadows on Saturday.
"I hadn't seen him for a few months," said Murray. "I actually saw him just now when I came off the court, which was nice."
Haase is the first hurdle of a fiendish-looking draw for the 27-year-old, and his results this year would suggest he will struggle to go deep into the tournament.
Since the Dimitrov loss, Murray has been beaten in the quarter-finals in Toronto and Cincinnati by Jo-Wilfried Tsonga and Roger Federer respectively.
He had chances in both matches only for his unhappy recent habit of losing leads to strike.
But Murray has been fortified by a post-Wimbledon training block in Miami with Mauresmo and the rest of his team, and looked confident and relaxed as he addressed the media.
"I feel good," he said. "I have had a great practice week, had good fun on the court, enjoyed it, and worked hard. I've been playing well."
The 2012 champion, who is seeded only eighth this year, took time away from the practice court on Friday for a day of watching sport.
First he saw Rory McIlroy fight back to make the cut at The Barclays tournament in New Jersey before spending his evening at Madison Square Garden for a basketball match between USA and Puerto Rico.
"It was fun," said Murray. "I have never been to watch golf live before. So for a first experience, watching the best player in the world was a pretty good experience and I really enjoyed it.
"I guess it's like pretty much any sport. When you watch them up close, it's impressive. Then in the evening I went to watch the basketball at Madison Square Garden.
"I love watching basketball. But to sit that close again and (see) those guys, they're huge guys, but just unbelievably quick, great athletes. It was a fun day for me."
One thing Murray almost certainly will not be watching is mum Judy's appearances on Strictly Come Dancing.
The Great Britain Fed Cup captain was confirmed earlier this week as the second contestant for this year's series of the TV show.
Murray said: "If it makes her happy, then I will support her. I'm not really into those shows, but she loves it. She watches it all the time, talks about it all the time. If she enjoys it, then I'm happy for her.
"I don't think I have ever seen her dance. It will be interesting."
