Liverpool manager Jurgen Klopp knows a good left back when he sees one.
The German brought in flying full back Andy Robertson from Hull for a bargain £8million three years ago and has been looking for cover for the Scotland captain.
The Premier League champions have found their man in Olympiacos left back Kostas Tsimikas in an £11.75m deal.
Here, Sportsmail takes a look at the 24-year-old who has made the move to Merseyside.
It’s a huge move in the career of Tsimikas. From the capital Athens he played in the youth set-ups for Neapoli Thessaloniki and Panserraikos prior to making the switch to Olympiacos in 2014.
He made his debut a year later as a teenager but was sent out on loan to gain more experience in 2016.
Tsimikas got valuable minutes under his belt at Esbjerg in Denmark and then at Willem II in Holland.
In his first loan spell he notched two goals and supplied two assists in 13 matches and during his time in Holland he scored six goals and recorded four assists in 37 appearances, including an impressive bicycle kick following a powerful, surging run.
The young full back did not find the net for Olympiacos after returning to the first-team fold in 2018 but supplied 12 assists in 86 matches.
After playing for his country at both Under 19 and U21 level, he has earned three senior international caps for Greece following his debut two years ago.
Tsimikas cemented his place as the first-choice left back last season and was highly regarded by Olympiacos, who only gave him a new contract until 2022 last year.
The Greece international had plenty of suitors from the Premier League in recent weeks.
Liverpool pipped Leicester to Tsimikas while the full back had also attracted interest from Premier League rivals Tottenham, Everton and Chelsea.
Tsimikas was in demand but the Reds capitalised on Olympiacos’ visit to England last week.
The club’s hierarchy held talks with the Greek outfit to finalise the details of the switch following their Europa League defeat by Wolves last Thursday.
Liverpool fans may have noticed Tsimikas in the Europa League this season as he put in impressive performances against both Arsenal and Wolves.
He also featured in the Champions League earlier in the season, playing in defeats by Bayern Munich and in Olympiacos’ 2-2 draw with Spurs in September.
In 46 appearances for Olympiacos during the 2019-20 campaign, he supplied seven assists.
The left back was part of the Olympiacos defence that managed to contain the lethal attacking force of Adama Traore last week.
The winger completed just two out of eight dribbles successfully, a 25 per cent success rate, which was his lowest since August 2019.
Finding back-up at left back has been a problem for Liverpool for some time. Veteran midfielder James Milner has regularly provided cover for Robertson at Anfield.
Alberto Moreno spent a year on the bench as he failed to earn Klopp’s trust while Joe Gomez and most recently Neco Williams have played in the problem position.
Tsimikas appears to be the solution to Liverpool’s dilemma and will be a more than a capable deputy to Robertson.
He boasts similar attributes to the 26-year-old with an engine to influence play at both ends of the pitch and the willingness and ability to carry the ball forward.
Both Robertson and Trent Alexander-Arnold on the opposite flank are crucial cogs in Liverpool’s winning system with the pair providing 27 assists combined last campaign.
The duo’s delivery for attackers is superb and Tsimikas is a player who likes to get forward and whip in a cross.
Being able to improve his game as an understudy to Robertson and with the guidance of Klopp, Tsimikas could be another sensational snip by the Reds boss.
