Wayne Rooney is at the centre of a row between Chelsea and Manchester United over a bid for the player which was rejected by the Old Trafford outfit today.
The Stamford Bridge outfit are certain United were responsible for that suggestion, which they insist was not true.
"Although the terms of that offer are confidential, for the avoidance of doubt and contrary to what is apparently being briefed to the press in Sydney, the proposed purchase does not include the transfer or loan of any players from Chelsea to Manchester United."
There has actually been no suggestion that United - currently in Sydney as part of a pre-season tour - either confirmed the bid, or put the names of Mata and Luiz into the public domain.
For their part, the Blues believe Mata and Luiz - both still on their summer break after featuring in the Confederations Cup - are key to their long-term plans and also want Rooney to be part of Jose Mourinho's second coming.
It does bring an additional twist to a story that is likely to rumble on for most of the summer.
Last week, Mourinho expressed his admiration for Rooney.
But the offer has been made with the England striker back in Manchester for treatment on a hamstring injury and at a time when he is annoyed at the depiction by Moyes of him being a back-up for Robin van Persie.
So deep is his fury, sources claimed he was "angry and confused" about Moyes' statement, it seems impossible his nine-year stay at Old Trafford can be salvaged.
That United should dismiss the offer so quickly is no surprise.
In recent weeks they have repeatedly insisted Rooney is not for sale, and the idea of selling to a domestic rival is particularly unpalatable.
Yet it is difficult to envisage how United can possibly hold that line right until the transfer window closes.
It increasingly appears Rooney's position is impossible, with United fans likely to turn against their one-time hero.
And for Moyes, it represents a tricky situation given he is attempting to bolster his squad rather than weaken it.
Yet Rooney's reaction to Moyes' comments has been the trigger for a further deterioration in the relationship between club and player.
Though it is thought Moyes did not mean the comments in the way they have come across, Rooney has reacted negatively.
Moyes had said: "Overall, my thought on Wayne is that if for any reason we had an injury to Robin van Persie we are going to need him and I want as many options as possible."
As far as Rooney is concerned, he is at the peak of his career and has no intention of playing second fiddle to anyone, or being reduced to the rank of a squad player.
With four Premier League titles and a Champions League winner's medal to his name, the 27-year-old does not believe he has anything to prove at United.
Yet now he feels as though he has been put on trial by Moyes.
After months of speculation about his future, and no statement of intent to stay from the player, it is now clear that unless there is some major repair work undertaken, Rooney will be leaving.
The manner of United's response is the first major test for Moyes and chief executive Ed Woodward since they replaced Sir Alex Ferguson and David Gill respectively at the beginning of the month.
