Wigan chairman Dave Whelan has told Sky Sports News that Manchester United have made cash offers for Antonio Valencia.
It was reported at the weekend that Premier League champions United and Primera Liga giants Real Madrid had bid in excess of £16million for the Ecuadorian.
Real - who have had a world-record £80m bid for United's Cristiano Ronaldo accepted - have since stated that they have not shown an interest in Valencia since January.
However, Whelan has declared that United have been in contact with JJB Stadium officials for the past two to three months and that they have also submitted initial offers.
He told Sky Sports News when asked about Valencia: "They (United) have been in touch with us and we will be starting negotiations very shortly, I would imagine.
"United have been in touch with us over Antonio for the last two or three months, expressing an interest and actually putting cash offers on the table.
"Those things have got to be picked up now. I think they were waiting to see if Ronaldo actually went to Real, which has happened."
He added: "Things will develop over the next seven to 14 days.
"The master, which is Sir Alex [Ferguson], he makes his moves when he is ready. He has strong interest in Antonio, there is no question in that.
"He had him watched practically every, single match last year. He has got a very strong interest in him. We are just sat on the fence now."
Whelan, though, is adamant that Wigan - who are currently without a manager following a backroom-staff compensation hitch in their attempts to appoint Roberto Martinez - are not eager to cash in on Valencia.
"We are not desperate to sell Antonio, I'm telling you. If I can keep that lad, I'm going to keep him. He is one brilliant player," added Whelan.
"So there is no pressure on me, or our football club to sell him. If Man United don't want to make a (written) offer, I'll be delighted and we will have him in our team next season."
But Whelan admits that he will not stand in the 23-year-old's way if he expresses a desire to move to Old Trafford and an asking price is met.
He said: "What is difficult is to stop a lad like Antonio Valencia, who has got ambition. It is difficult to stop a footballer, who wants to get to the very, very top of the ladder.
"I would never stand in the way of a footballer who can go to bigger and better clubs, and you can't get bigger and better than Man United.
"If Antonio Valencia says to me, 'chairman, I want to go to Manchester United' and we get the right fee, the deal will be done."
