North London duo eye 'Terminator' Cetin
The imposing 28-year-old centre-back has spent his entire career in his homeland, playing for five other clubs before joining Galatasaray in 2007, for whom he has made 61 league appearances.
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.
And as a result, Premier League duo Arsenal and Spurs are thought to be considering swoops for the powerful defender to help add some steel to their respective line-ups.
The enforcer's presence even intimidated the usually indomitable Chelsea forward Didier Drogba in a February international between Turkey and Ivory Coast, with the striker revealing after the match:
"I have never struggled like this against any defence in the Premier League. Servet is devilish. I could hear him breathe and it sent chills down the back of my neck."
