When it comes to the definition of an imposing centre-back Sotirios Kyrgiakos ticks all the boxes.
The 6ft 4" pony-tailed defender was not a man to be messed with and his unexpected arrival at Anfield, 13 years ago to the day, provided a very obvious key attribute. Performing well up against troublesome target man Kevin Davies on his Liverpool debut against Bolton Wanderers, Rafa Benitez explained in fairly plain language why 'The Greek' - as he would commonly be known on the Kop - had been brought to the club.
"What has Sotirios brought? Headers. He is strong and he likes the challenge," said Benitez. "It is something that we needed and right now he is doing well. His attitude has been contagious. Kevin Davies is very strong and it is not easy to stop him in the air, so Sotirios did really well. He lost one tooth in the game and that shows how hard it can be."
