Palermo president Maurizio Zamparini has revealed that a £30m bid has been tabled for striker Paulo Dybala, but refused to disclose the club that made it.
Manchester United, Arsenal and Juventus are all said to be keen on the 21-year-old, who has scored 12 goals in 25 appearances this season.
Zamparini is quoted by The Express as saying: "Has Dybala already been picked up by Juve? Absolutely not.
"I already have a €40m (£30m) offer in my hand, but if someone else gets into the race then we'll see what happens. Were Manchester United behind this offer? I won't tell you the name of the club, not even if you torture me!"
Dybala previously joked that he would "swim to Barcelona if they came knocking".
