Newcastle midfielder Kieron Dyer has been given permission to speak to West Ham after the two clubs tonight agreed an undisclosed fee.

Manager Sam Allardyce had earlier insisted a reported £4million bid for the England international was well below Newcastle's valuation.

Dyer is understood to be keen to move south to be closer to his family.

Reports today claimed Dyer has been subjected to abuse from some Newcastle fans since it became known he was hoping to leave.

Chairman Chris Mort has expressed his concern at the effect that could have on attempts to overhaul the squad.

Dyer was booed during the weekend's friendly win over Juventus and it is alleged that eggs were recently thrown at his house.

Mort warned: "We have to make all our current players and potential new signings see Newcastle as a great place to live.  It would be disastrous for this sort of behaviour to be repeated."
