Manchester United's owners have warned Real Madrid that Cristiano Ronaldo is not for sale at any price.
The Glazer family are adamant that they do not need even a reported world-record £70million transfer fee to boost the club's coffers despite reportedly incurring around £600million of debt when they financed their takeover at Old Trafford three years ago.
Real Madrid remain intent on prising the 23-year-old Portugal international away from the Red Devils, but the American owners have warned the Spanish giants that they are wasting their time.
Ronaldo, who is currently away on international duty at Euro 2008, has so far refused to pledge his future to United despite being just 12 months into a five-year contract.
"There is no way Ronaldo is for sale at all, even if he puts in a transfer request," a source close to the Glazers told The Sun.
"Anyone thinking the debt comes into this is totally ignorant of the facts. The debt is covered comfortably by the interest payments.
"In the three years the family have owned the club, they have shown a clear track record of investment which will continue.
"The Glazers have never meddled in anything the manager has done and never will interfere. All decisions on buying and selling are down to him and if he wants new players the money is there.
"There is no truth in any insinuation we would be willing to talk to Real Madrid about selling Cristiano. That is nonsense.
"The next move is for the manager to talk to Cristiano when he returns for training."
