Newcastle have rejected a new £23million bid from Tottenham for striker Andy Carroll, Sky Sports News understands.
The England international has enjoyed an impressive debut season in the Premier League, bagging 11 Premier League goals before being sidelined by a thigh injury.
Carroll's displays in leading the line for the Magpies has attracted interest from a number of rival top-flight teams, with Harry Redknapp keen to bring the powerful forward to White Hart Lane.
The North East club are determined to retain the services of their star man and have rebuffed all offers for his services, with Spurs' latest offer drawing a terse response.
Not for sale
A high-ranking Newcastle official told Sky Sports News: "The club would like to make it clear for the very last time that Carroll is simply not for sale."
The source went on to describe the bid from Tottenham as 'paltry in the current climate'.
Magpies boss Alan Pardew has always stressed his determination to keep hold of his key players during January as he looks to establish the club back in the top flight.
And with the transfer window due to close at 11pm on Monday, it remains to be seen if Spurs will return with an improved offer.
