Liverpool have taken no time in signing Greek defender Kontas Tsimikas from Olympiakos for £11.7m on a five-year contract.
“I’m very happy, I’m very proud to be here,” said the 24-year-old.
“It’s an honour to be here and I will give my best. For me, the biggest club in the world.”
After failing to negotiate a deal for Norwich City’s Jamal Lewis, Jurgen Klopp swiftly turned his attention to Tsimikas.
“We have watched Kostas for a long time and are really happy that he has joined us,” said the Liverpool boss. “It’s the perfect news before we come back together very soon.
“He is a very good footballer with an attitude to win and to compete, and I really like his mentality. It fits perfectly with the mood and the desire we have in our dressing room already.
“Kostas knows from personal experience what is required to challenge and succeed domestically and in the Champions League, and he is ambitious for more – just like us.”
