Jurgen Klopp says new signing Kostas Tsimikas is "really right on track" with his career development and fits the mould of what he wants from his Liverpool full-backs.

Tsimikas completed his move to Anfield from Olympiacos last week in a deal reported to be worth £11.7million.

On the face of it, signing a new left-back would not have appeared high on the list of priorities for the Reds given the consistently brilliant form of Andy Robertson, who provided 12 assists and two goals in Liverpool's Premier League title-winning team.

But a lack of cover in the position means veteran James Milner has mainly filled the void on the rare occasions Robertson has been unavailable.

Klopp explained that the importance of full-backs to Liverpool's style of play was what made the Greece international such an attractive proposition.

"Kostas is a signing which just shows what we are looking for, what we need," the Liverpool boss told the club's official website.

"I think the left-back position was now not a position where the people out there would have thought, 'we need another player' and stuff like this.

"It worked out pretty well, Millie played there from time to time but we cannot take any risk or we should take as little risk as possible.

"Our full-backs in the way we play are so important with the skills they have, the speed they have, the crosses they bring in and stuff like this.

"When I saw Kostas the first time, I thought, 'is it possible to get somebody like him?' Meanwhile, he's not the most experienced player because he started a little bit later with a proper career.

"But in the last two or three years, he's really right on track and then has started building his career obviously.
