The Liverpool manager believes his new recruit will fit right in for the Reds with his "attitude to win and compete"
Tsimikas joined Liverpool from Olympiacos few days ago in a £11.75m deal and signed a five-year contract with the champions.
The 24-year-old Greece international who featured against Wolves in the Europa League last week, is expected to provide the much-needed competition for Andy Robertson on Merseyside.
And speaking to the Liverpool official website, Klopp believe the former Greece Super League starman is perfect addition for that role.
“We have watched Kostas for a long time and are really happy that he has joined us. It’s the perfect news before we come back together very soon," Klopp said.
"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.
"He has showed already at a young age he can experience football in a different country and do well – and he has been a big part of the success Olympiacos has had to win their title this season and in their European campaigns.
"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.
"He has come up against some very tough opponents in the past couple of seasons and done well and we know he relishes the challenge, which is perfect for us.
"For that reason we are delighted to know we’ll have him with us for the years ahead. I’m so pleased."
