The Chilean ace has been strongly linked with moving to Barcelona in the summer, with the player stating that the Spanish and European champions would be a "splendid" place for him to further his career.
However, talks between the Italian and Spanish clubs are believed to have reached a stalemate as Udinese are planning to honour their valuation of Sanchez, which Goal.com exclusively revealed in May to be worth €30m.
And City, who have been credited with an interest in Sanchez already, will move in quickly to secure the player with a €30m proposal, hoping to beat the Champions League winners to the punch.
Reports in Italy suggest that the Citizens will meet with Udinese tomorrow in what could prove to be a decisive day for the 22-year-old's future.
