The Chilean youngster has been linked with a January move to Manchester United.
“I’d say you need more than €20m to sign Sanchez,” Udinese owner Pozzo told the Gazzetta dello Sport.
“In any case, I don’t think this’ll be an issue. He is a world class player, but needs a few years to mature in Udine so he can make the real step up in quality.
“When he is able to score 10-12 goals per season, then we can give the all-clear for a sale.
“As for the other players, the January transfer window is not only closed, but also bricked up. We are not selling anybody and I don’t see the need to sign anyone either.
“Gokhan Inler won’t be leaving and neither will Antonio Floro Flores.”
