Aston Villa defender Ciaran Clark is set to undergo a medical at Newcastle on Tuesday, according to a reliable BBC journalist.

Midlands reporter Pat Murphy broke the news on his personal Twitter account on Tuesday morning that the player looks set for a move to St James Park.

Newcastle activated the centre-back’s £5.1 million release clause on Monday with the player now set to depart for Villa’s Championship rivals.

Murphy said the Midlands club wanted the 26-year-old to stay as they push for promotion following relegation last term.

Clark is a graduate of the Villa academy and has racked up 159 appearances for the club since making his debut as teenager in 2009.

He is headed for a medical at Newcastle as the club also close in on the signing of midfielder Mohamed Diame from Hull.

The north-east giants activated a £4.5 million release clause in Diame’s contract on Monday morning.

The Republic of Ireland international featured on two occasions for his home country during the recently concluded European Championships in France.

Pre-season for Roberto Di Matteo’s side this season has suggested that the Italian’s first choice centre-back pairing is £5million summer signing Tommy Elphick and academy graduate Nathan Baker with Jores Okore as back-up.

Villa supporters will react with mixed views as some would feel the club should not be selling to a direct rival, while others will be glad to see the back of a player who played a part in the Villans conceding 76 goals last season.
