Benitez admits he is delighted to have landed his man and feels the centre-back can become a genuine threat at set pieces for his new team.
"Since Sami left the club, we have been looking for a player with quality and Sotirios is the kind of player we were looking for," the boss told his weekly press conference at Melwood.
"Our fans have knowledge of international football and he has played in Scotland, Germany and Greece, so I think everyone will know he is a strong, aggressive player who is good in the air.
"He will be a physical presence in both penalty areas, which is good for us because he is exactly the kind of player we were looking for. He can give us something different."
It is true that we are missing goals from our CBs at FKs and especially corners. Sami was brilliant and so much of a threat that he created more space for those around him. We have been missing this - Agger should score more but usually puts it wide, Carra is never a threat and Skrtel - for some reason, though he should be - almost never is as well.
Hopefully Kyrgiakos won't get many games because Carra / Skrtel / Agger will stay fit, however it will be nice to have the added threat at set-pieces in their penalty box again and maybe take some pressure off Torres too.
