Joey Barton looks set to depart the Magpies at the end of the season, according to the Free Bets website. The 28-year-old, who has a year to run on his present contract, was unable to agree terms on a new deal.
Magpies boss Alan Pardew has been quoted as wanting to retain Barton, who joined Newcastle from Manchester City in July 2007 for £5.8m.
Huyton-born Barton has scored eight goals in 82 appearances at Newcastle.
Barton has previously stated his happiness at Newcastle, and was even quoted as wanting to extend the contract in February of this year.
