MANCHESTER UNITED target Alexis Sanchez has seen a £30million bid from an unnamed club turned down by Udinese. The Chilean winger, 22, is one of the hottest properties in Europe, with Barcelona, Chelsea and Manchester City also interested. But Italian side Udinese have qualified for the preliminary stages of the Champions League, with club owner Giampoalo Pozzo refusing to sell unless the fee is astronomical. He said: "For me Sanchez is worth the same as Lionel Messi. It's difficult to find other players of his level. "Only two or three players are born like him in a given generation. "We have an offer of £30million which we have turned down. I do not want to name the club, out of respect. "Sanchez is young and we would like him to stay for another year. Besides, we believe he is worth much more. Sanchez, who scored 12 goals in 31 league appearances for Udinese this season, is under contract with the Italian side until June 2014.
