Sotiris Kyrgiakos admits he is turning his back on AEK Athens to join Liverpool because it is the 'biggest challenge of his career'.
The Reds have agreed a deal for the Greece international, as originally revealed by skysports.com, which is believed to be worth £1.5million.
Kyrgiakos had previously announced that his long-term future was at AEK and, with a move to Anfield imminent, he has therefore explained his about turn.
"Last week I said I was an AEK player for the next four years and meant that," he said on his official website.
"But then I received the biggest challenge of my career.
"I fully understand it came at the worst possible moment for the team, but the fact that I had the chance to play for Liverpool is a huge challenge."
