Tonali is under contract at St. James’ Park till the summer of 2029, with an option to extend the deal by another 12 months till the end of the 2029-30 season.
Despite this, the Italian midfielder has been linked with several sides including Manchester City and Manchester United who are reportedly keen on stealing away the playmaker at the end of the season.
Chronicle Live report that Newcastle are frustrated with Tonali's agent, Giuseppe Riso for speaking openly about leaving the Premier League side, but the club are said to be calm considering the length of his contract.
Manchester United midfielder Casemiro will leave the club at the end of the season and the Red Devils are said to be keen on replacing him with one of Elliot Anderson, Carlos Baleba or Tonali in the coming months.
Kobbie Mainoo looks set to sign a new contract, along with centre-back Harry Maguire, but it is not enough for manager Michael Carrick heading into the new campaign as they seek to strengthen the side.
Reports state that Newcastle could demand £100M for the 25-year-old which may deter many clubs from trying to open talks with the Italian.
Tonali is expected to keep his place in the Italy side when the Azzurri face Bosnia and Herzegovina on Tuesday night as they seek to book their place in the World Cup.
