Barcelona mull move for Cetin
The 6ft 4in stopper - whose nicknames range from 'Bionic Cetin' to 'Terminator Cetin' - has won 42 caps for his country, helping Turkey reach the semi-finals of Euro 2008.
As a result, Premier League duo Arsenal and Spurs are thought to be mulling moves for the defender to help add some steel to their sides.
However, according to Cadena SER, they could face stiff competition for the enforcer's services from Catalan giants Barcelona, who will lose defensive duo Yaya Toure and Seydou Keita to the African Cup of Nations in the New Year.
The player's agent recently revealed that Premier League clubs had expressed an interest in Cetin.
"There has been no concrete contact from the clubs in question. And neither of those clubs have contacted Galatasaray directly, only a French club has enquiried about Cetin," Mithat Halis told Sport.co.uk.
"However, top Premier League clubs are watching the player. And who knows? In January, he could move, but only for the right price. Which is at least £10 million because he is a top player. I can say no more."
