AC Milan vice-president Adriano Galliani has scotched reports that Alexandre Pato could be set for a move to the Barclays Premier League in January, amid reported interest from Chelsea.
The 22-year-old striker has been linked with a move to west London if the Serie A giants agree a deal to bring want-away Manchester City striker Carlos Tevez to the San Siro.
Blues boss Andre Villas-Boas is a known admirer of the Brazilian star, and is believed to be considering a bid to bring him to Stamford Bridge when the transfer window reopens.
As the Portuguese tactician continues his overhaul of the Chelsea playing squad, Pato is one player who has been earmarked as a potential candidate to spearhead the club's attack in the many years to come.
However, any hopes the Blues may have had of signing the South American striker have now been dealt a significant blow after Galliani ruled out a sale.
"There is no chance that Pato can leave," he said. "If Tevez signs then it will be because Cassano has had the problem that we all know about.
"Pato, Robinho and Zlatan Ibrahimovic are untouchable. This isn't a brilliant moment for him, but Pato is Pato. He scores almost a goal every two games. There is no Pato problem."
