Olympiacos boss Pedro Martins says Kostas Tsimikas deserves his move to Liverpool, despite the fact he will miss him at the Greek club.

Left-back Tsimikas, 24, made a switch to the Premier League champions last week.

And Martins says the Reds have a quality player on their hands.

"He deserves this opportunity," Martins tells Goal. "He improved so much, and now he will be playing in the best championship in the world, and for one of the best teams in the world.

"I'm not happy that I have lost such a good player, but I am happy for Kostas. I spoke with him after he signed his contract, and he was so happy. This is one of his dreams."

"He's a fighter, who plays with passion. He is a strong personality, very strong mentally.

"He's available to learn. I know that Klopp will find that, he will listen with his full attention. He wants to improve, and he's a good professional. He knows he will have to work hard to play. He knows that.

"He knows he will have to be patient, for sure. Robertson has had a fantastic season and is a fantastic player. But Kostas is ready for everything. He will be patient and he will work, every single day."

On playing under Klopp, Martines added: "He was always very involved in our attacking play, and that of course is why Klopp wanted to sign him. He knows what he can bring to Liverpool in that sense. For the game of Klopp, Tsimikas is perfect. He is amazing for Klopp. He gives that energy, width, offensive threat. That's how we played too."
