Newcastle defender Mike Williamson will be used as a bartering tool in the club's attempts to sign Brighton defender Lewis Dunk
It is believed that Dunk, 23, who is highly rated by clubs of the Football League, is valued at around £5 million by the Championship outfit.
They rejected a £4m offer from Fulham earlier in the summer, according to the Daily Mail, and manager Chris Hughton spoke of his determination to keep 'one of his best players'.
However, Premier League club Newcastle are now keen to test the Seagull's resolve. Reports suggest that Magpies boss Steve McClaren has this week told several players they are no longer wanted at St James' Park - and veteran Williamson is among them.
It was former Toon manager Hughton who brought the central defender, who has since made 169 appearances for the club, to Newcastle in 2010 and he is keen to be reunited with the 31-year-old.
This interest could benefit the club, who will reportedly look to include Williamson in a potential swap deal. Dunk netted an impressive seven goals in 43 appearances from defence last season and McClaren is understood to be a long-term admirer.
The 23-year-old could strengthen a Newcastle defence that has been seriously lacking in recent months. Would he be an astute addition on Tyneside - especially if Williamson went the other way?
