Mohamed Diame has had his release clause triggered by Newcastle

Newcastle United have triggered the release clause of Hull midfielder Mohamed Diame, according to Sky sources.

A fee between the two clubs has been agreed after Newcastle activated the clause of £4.5m with the player lined up to have a medical on Tuesday.

The 29-year-old, who joined Hull from West Ham in 2014, has made 50 appearances for the Tigers and scored 13 goals.

However, the Tigers will reportedly offer Diame a new contract and hopes that he joins them on their pre-season trip to Austria on Tuesday for fixtures against Caykur Rizespor and Torino ahead of their Premier League opener against champions Leicester on August 13.

And it was the Senegal international who struck a sensational winning goal 18 minutes from time in the Championship play-off final last season as managerless Hull join Burnley and Middlesbrough as the Premier League's new boys for the 2016/17 campaign.

A graduate of the Clarefontaine academy, Diame has been in England since the 2009 season when he joined Wigan Athletic from Rayo Vallecano after a promotion-clinching campaign.

After three years at Wigan, Diame moved to play for West Ham under Sam Allardyce before joining Hull in 2014.
